Chiral symmetry restoration and strong CP violation in a strong magnetic background
Eduardo S. Fraga, Ana Júlia Mizher
Motivated by the phenomenological scenario of the chiral magnetic effect that can be possibly found in high-energy heavy ion collisions, we study the role of very intense magnetic…
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…
Finite-size effects and the search for the critical endpoint in heavy ion collisions
Leticia F. Palhares, Eduardo S. Fraga, Takeshi Kodama
We discuss how the finiteness of the system created in a heavy-ion collision affects possible signatures of the QCD critical endpoint. We show sizable results for the modifications…
Nucleation of quark matter in protoneutron star matter
B. W. Mintz, E. S. Fraga, G. Pagliara +1
The phase transition from hadronic to quark matter may take place already during the early post-bounce stage of core collapse supernovae when matter is still hot and lepton rich. I…
Chiral transition in a finite system and possible use of finite size scaling in relativistic heavy ion collisions
L. F. Palhares, E. S. Fraga, T. Kodama
We investigate finite-size effects on the chiral phase diagram of strong interactions within the linear sigma model coupled to quarks. We estimate the modification of the pseudocri…
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…
