Research activities
My research activity has focused on issues ranging from fundamental interactions to statistical and condensed matter physics, from lattice gauge theories to quantum many-body systems, etc. Most used frameworks are quantum field theories using perturbative and nonperturbative approaches, renormalization-group theory, lattice field theories, numerical simulations, which allow us to address problems arising in different physical contexts. Some recent research lines are: (i) Coherent and dissipative quantum dynamics of many-body systems at quantum first-order and continuous phase transitions; (ii) Critical phenomena at quantum and thermal transitions in several physically interesting systems; (iii) Interplay between global and gauge symmetries in lattice gauge theories with scalar and fermion fields; (iv) Emerging gauge theories in condensed matter physics; (v) Nonperturbative aspects of the theory of the strong interactions, i.e. the quantum chromodynamics (QCD).
