High Energy Physics

About

My research activity focuses on various aspects of quantum information, holography and non-Lorentzian limits. During my career, I explored several notions of complexity - a tool that quantifies the difficulty of preparing a state or implementing a unitary operation - both in gravitational physics and quantum systems. I employed holography to study features of defects and boundaries quantified by entanglement and energy transport. I investigated properties of de Sitter spacetime, which describes the early and late stages of evolution of our universe. Finally, I explored the holographic duality in corners obtained by performing non-Lorentzian limits
