Non-Markovian expansion in quantum dissipative systems
E. S. Fraga, G. Krein, L. F. Palhares
We consider the non-Markovian Langevin evolution of a dissipative dynamical system in quantum mechanics in the path integral formalism. After discussing the role of the frequency c…
Nonperturbative Yukawa theory at finite density and temperature
Eduardo S. Fraga, Leticia F. Palhares, Marcus Benghi Pinto
In-medium Yukawa theory is part of the thermodynamics of the Standard Model of particle physics and is one of the main building blocks of most effective field theories of fermionic…
Mass and chemical asymmetry in QCD matter
L. F. Palhares, E. S. Fraga, C. Villavicencio
We consider two-flavor asymmetric QCD combined with a low-energy effective model inspired by chiral perturbation theory and lattice data to investigate the effects of masses, isosp…
Perturbative Yukawa theory at finite density: the role of masses and renormalization group flow at two loops
Letícia F. Palhares, Eduardo S. Fraga
Yukawa theory at vanishing temperature provides (one of the ingredients for) an effective description of the thermodynamics of a variety of cold and dense fermionic systems. We stu…
Dissipation and memory effects in pure glue deconfinement
E. S. Fraga, T. Kodama, G. Krein +2
We investigate the effects of dissipation in the deconfining transition for a pure SU(2) gauge theory. Using an effective model for the order parameter, we study its Langevin evolu…
