Theoretical physics

The theory group focuses on the study of the theory and phenomenology of fundamental interactions. The main research areas include gravity and cosmology, accelerator and astroparticle phenomenology, nuclear physics, quantum field theory and string theory, statistical and quantum physics.

The major quantum gravity problems under investigation include the origin and dynamics of the primordial universe, black holes, dark matter and dark energy. The study of particle interactions at the energy or intensity frontier at accelerators aims to understand the origin of neutrino masses and the matter-antimatter asymmetry, the possibility of new physics beyond the electroweak scale, the phases of strong interactions and nuclear systems. The main research lines in fundamental physics involve non-perturbative aspects of quantum field theory, the dynamics of supersymmetric theories and the connection between string theory and low-energy phenomenology. These are investigated using renormalization group techniques, integrability, duality, generalized symmetries, branes and extra dimensions. The study of many-body quantum systems relies on numerical simulations and modern techniques in statistical field theory. Studies of quantum information and computation are pursued alongside experimental manipulations of atomic structures.
