Alexander Balatsky's field of research is theoretical condensed matter physics. His recent work has mainly been in strongly correlated materials, unconventional superconductivity, and biomolecular electronics.
Professor Axel Brandenburg received his PhD at the University of Helsinki in 1990. After two postdocs at Nordita in Copenhagen and at the High Altitude Observatory at the National Center for Atmospheric Research in Boulder/Colorado he returned to Nordita as Assistant Professor for just over a year before he went in 1996 as full Professor of Applied Mathematics to the University of Newcastle upon Tyne. In 2000 he moved once again to Nordita, this time as full professor. He became professor at the Department of Astronomy in Stockholm when Nordita moved from Denmark to Sweden in 2007
Axel Brandenburg is working in the field of astrophysical fluid dynamics and has also an interest in selected topics of astrobiology. He is particularly interested in the question of magnetic field generation from turbulent motions with applications to the Sun and stars, accretion discs, galaxies, and the early Universe.
His work on accretion disc turbulence was the first to show that the magneto-rotational and dynamo instabilities lead to a sustained doubly-positive feedback. Recently, he contributed to clarifying the long-standing question of the suppression of the dynamo effect in generating large-scale fields. He is also responsible for the maintenance of the Pencil Code, which is a public domain code (
pencil-code.googlecode.com) for astrophysical fluid dynamics that is well suited for large clusters with distributed memory.
In 2009 he received funding from the European Research Council for a project on Astrophysical Dynamos with a volume of 2.22 M € to support 4 PhD students, 4 post-docs, one assistant professor and several senior visitors.

Paolo Di Vecchia received his degree (Italian Laurea) at the University of Rome in 1966. After a post-doctoral fellowship at the Laboratori Nazionali di Frascati he was offered a permanent position there. After two-year positions at MIT and CERN he became Assistant Professor at Nordita, 1974-1978. After another year at CERN he became Professor first at the Freie Universität in Berlin in 1979 and then at the University of Wuppertal, 1980 to 1986. He came to Nordita in February 1986.
Paolo has worked and continues to work on the theory of elementary particles by using perturbative and non-perturbative methods both in field and string theories. His recent work has dealt with the extension of the AdS/CFT correspondence to less supersymmetric and non-conformal gauge theories deriving many properties of these theories, as the beta-function and the gaugino condensate of N=1 super Yang-Mills, from the supergravity solution. Another activity has been the construction of the four-dimensional low-energy Lagrangian from toroidal compactifications in magnetized D branes models that have the important property of generating chiral matter necessary for describing quarks and leptons. In this framework, he has computed the moduli dependence of the Kaehler metrics and of the Yukawa couplings using both stringy instantons and field theoretical methods. Most recently, he has studied high-energy scattering of closed strings on a stack of D branes in various regimes of impact parameter and 't Hooft coupling.
Since 1994, he has coordinated the organization of Nordic meetings in string theory bringing together Nordic researchers and students twice a year to learn about recent developments in the field. He has organized summer schools in field and string theory for Nordic students and supervised Nordic students. He was elected in 2003 member of the Det Kongelige Norske Videnskabers Selskab.
Ralf Eichhorn received his PhD from the University of Augsburg in 2000. After postdoctorial work in Augsburg and Bielefeld, he joined Nordita in January 2009. His general research interest is on the statistical mechanics of complex systems with application to biophysical problems.
Ralf's current research activities are centered around the theory of transport processes in non-equilibrium systems, where thermal noise typically plays a dominant role. Apart from studying idealized stochastic models, Ralf is also interested in developing concrete realizations of such transport phenomena, aiming at biophysical applications in microfluidic devices (lab-on-a-chip) for the separation, purification or mixing of colloidal particles and complex biomolecules like DNA or proteins. This is motivated by the vision of a lab-on-a-chip, which combines all preparational and analytical steps of a diagnostic device in a single microfluidic system. A further direction in Ralf's research covers the dynamic aspects of molecular recognition. Molecular recognition of two biomolecules occurs due to (non-specific) interactions between complementary regions on their surfaces. Within the framework of coarse-grained models for the molecules, the dynamic aspects of the recognition process in the crowded environment of a cell are studied. More recently, Ralf became interested in stochastic thermodynamics, a new field in non-equilibrium statistical mechanics addressing the problem of generalizing and extending concepts from equilibrium statistical physics to the non-equilibrium realm.
Ralf has intense collaborations with scientists at KTH and has established contacts to several groups in the Nordic countries (e.g., Aarhus, Lund, Gothenburg). He organized two "Nordic Workshops on Statistical Physics" (March 2010 and Feb 2011), is co-organizer of a workshop on DNA self-assembly (May 2011) and of two four-week scientific programs at Nordita (fall 2011 and spring 2012). Moreover, Ralf co-organizes an international seminar series on "Complex systems and biological physics".
Troels Harmark received his PhD from the Niels Bohr Institute, Copenhagen in August 2001. In September 2001 he joined the String Theory group at Harvard University that had granted him a postdoctoral fellowship. In September 2003 he started an Assistant Professor position at the High-Energy Theory and Theoretical Cosmology group at the Niels Bohr Institute payed by a 3-year grant from the Danish Research Foundation, and subsequently he continued a new 3-year grant from the Carlsberg Foundation as Research Associate Professor. He joined Nordita in October 2009 for a 5-year Assistant Professor position.
Troels' research is focused on aspects of black holes, string theory and the AdS/CFT correspondence. He has made various contributions to the field of higher-dimensional black holes, including the characterization of them and finding a new effective description of black holes that also has applications to the study of various types of phase transitions in strongly coupled quantum field theories via the AdS/CFT correspondence. He has a long-standing independent research programme devoted to finding a quantum mechanical description of black holes via the AdS/CFT correspondence. Finally, he has made contributions to the field of integrability of the spectrum of strings in the AdS/CFT correspondence.
Currently Troels has several active collaborations with scientists in Barcelona, Copenhagen, Crete, Durham, Perugia and Stockholm. In particular he has a strong connection to the High-Energy Theory group at the Niels Bohr Institute, Copenhagen. He is a co-organizer of the 2012 Nordita workshop program "The Holographic Way: String Theory, Gauge Theory and Black Holes".
John Hertz received his PhD from the University of Pennsylvania in 1970. After a postdoc at the Cavendish Laboratory, University of Cambridge, he joined the faculty of the James Franck Institute, University of Chicago as an Assistant Professor. He became Professor at Nordita in Copenhagen in 1980. Since 2007 he has also been Professor at the Niels Bohr Institute and, since 2014, visiting Professor in the Department of Neuroscience, Faculty of Health Sciences at Copenhagen University. He divides his time between Copenhagen and Stockholm.
Early in his career, John worked in condensed matter theory, particularly on magnetism in systems with highly correlated electrons and on phase transitions, which led to his well-known work on quantum critical phenomena. He then turned to the statistical mechanics of disordered systems, particularly spin glasses. This, in turn, led him to develop an interest in neural networks. With Anders Krogh and Richard Palmer, he wrote what is still a standard book on artificial networks. In recent years, working with Yasser Roudi (Norwegian University of Science and Technology), Erik Aurell (KTH) and Joanna Tyrcha (Stockholm University) he focused on biological networks, particularly on the dynamics of neural networks in the neocortex, the problem of inferring connectivity (and other network features) from recorded spike trains, and stochastic properties of protein and gene networks in cells. His current work, in collaboration with Joanna Tyrcha, is on training neural networks to compose music.
His collaborative activity in the Nordic region includes organizing two Nordic networks on neural computation, teaching and collaboration with groups in Norway and Sweden, numerous summer schools and conferences, and supervision of MS and PhD students.

Florian Niedermann received his PhD from the Ludwig Maximilian University of Munich in 2016. He then held a postdoc position at the University of Nottingham until 2018 and one at the Centre for Cosmology and Particle Physics Phenomenology in Denmark until 2020. He joined Nordita in the same year as a fellow in cosmology before he became a Nordita Assistant Professor in 2022 after winning a starting grant from the Swedish Research Council.
Florian’s research interest sits at the crossroads between particle physics and cosmology. In his past research, he explored the phenomenology and theoretical consistency of braneworld models, which describe our Universe as a hypersurface in a higher dimensional spacetime. He also worked on gravitational approaches to address the cosmological constant or electroweak hierarchy problem and employed effective field theories for dark energy model building. Most recently, he has been interested in low-energy phase transitions that take place in the dark sector during the CMB epoch. They constitute a phenomenologically promising framework to address recently found tensions in cosmological data sets while providing a theoretically consistent playground to address particle physics challenges such as the neutrino mass generation or the origin of the dark sector. At the same time, their unique signatures can be searched for in collider experiments, the CMB power spectra, the large-scale structure of our Universe and gravitational waves.
Currently, Florian has active collaborations with scientists in Stockholm, Denmark (Odense and Aarhus), Nottingham, and Munich.

Alexandra Veledina got her PhD from the University of Oulu, Finland, in 2014. She made a short postdoc at the University of Turku before moving to Stockholm as Nordita fellow in 2016. Since September 2017, she is Nordic assistant professor on a joint appointment with the University of Turku, Finland.
Her research is in the field of radiative processes in nearly-Maxwellian relativistic plasmas. In particular, her works are concentrated on modeling spectral and temporal characteristics of accreting compact objects such as black holes and neutron stars. She developed an accretion flow model capable of explaining many enigmatic multiwavelength observations obtained recently: correlated fast optical and X-ray variability, quasi-periodic oscillations and strong non-thermal infrared/optical flares. Her works raised attention to the importance of combining spectral and timing techniques.
Alexandra continues to work with astrophysical accretion flows, now paying more attention to the flow microphysics, rather than the observed characteristics. She plans to develop an MHD code capable of describing dynamics of accretion flow with non-Maxwellian electrons, relevant to black hole accretion environment.
Dmytro Volin received his PhD from the Université Paris-Sud XI in September 2009. His thesis was conducted and supervised at the Institut de Physique Théorique, Saclay. From October 2009 till October 2011 he had a postdoctoral position at the Pennsylvania State Univeristy, then he moved to Sweden to join Nordita for his second postdoc.
Dmytro's main interests are strongly interacting field theories and integrable systems, with emphasis on the integrability in AdS/CFT. In his works, he contributed to the solution of the AdS/CFT spectral problem, in particular to the solution of crossing equations and to a pioneer derivation of an AdS/CFT analog of Destri-de Vega equations. At present he is working on the bootstrap program for integrable systems at finite volume. This is in line with one of his long-term goals: to understand microscopic mechanisms behind the AdS/CFT duality, in N=4 SYM and beyond, without direct appeal to string theory.
Currently he has several active collaborations with scientists from France, Belgium, UK and USA. Dmytro is teaching an advanced online course on quantum integrability.
John S. Wettlaufer is the A.M. Bateman Professor of Geophysics, Physics and Applied Mathematics at Yale University. His training is in the statistical physics of phase transitions but over the years it has branched out substantially across many disciplines in soft condensed matter physics and applied mathematics with impinging upon biophysics, geophysics and most recently, due to his time here previously, astrophysics.
His stay at Nordita in the fall of 2011 is supported by the Wenner-Gren Foundation, and he has been awarded the Tage Erlander Guest Professorship for 2012. The holder of this chair is appointed by invitation from the Swedish Research Council.
John will be working on the stochastic dynamics generally with applications to abrupt changes in Arctic climate and in fluid dynamics generally. In the former case, the basic problem is one of predicting the future using imperfect and highly variable global climate computer models versus the questionable activity of extrapolating to the future using a 31 year time series of high resolution satellite data. This leaves a spate of possibilities for "simple" mathematical models, rigorous studies of the origin and nature of variability and periodicity, and a focus on the multiplicity of time scales embedded in the data, examined in the context of the singularity spectrum of multifractals. These approaches have an origin in the statistical mechanics of fluctuating systems with major insights originating in stochastic and numerical models of turbulence, dynamos and a wide variety of other systems. He hopes also to begin the process of incorporating the microphysical conditions for planetary accretion studied during his previous visit into the pencil code.
