New Class of Compact Stars at High Density
Eduardo S. Fraga, Robert D. Pisarski, Jurgen Schaffner-Bielich
We discuss the equation of state for cold, dense quark matter in perturbation theory, and how it might match onto that of hadronic matter. Certain choices of the renormalization sc…
Equilibration Time Scales in Homogeneous Bose-Einstein Condensate Dynamics
Daniel G. Barci, Eduardo S. Fraga, Marcelo Gleiser +1
We study the nonequilibrium growth of a weakly interacting homogeneous Bose gas after a quench from a high-temperature state to a temperature below the Bose-Einstein critical conde…
Improved semiclassical density matrix: taming caustics
C. A. A. de Carvalho, R. M. Cavalcanti, E. S. Fraga +1
We present a simple method to deal with caustics in the semiclassical approximation to the thermal density matrix of a particle moving on the line. For simplicity, only its diagona…
Microscopic Evolution of a Weakly Interacting Homogeneous Bose Gas
D. G. Barci, E. S. Fraga, Rudnei O. Ramos
We provide a detailed description of the nonequilibrium time evolution of an interacting homogeneous Bose-Einstein condensate. We use a nonperturbative in-medium quantum field theo…
Small, Dense Quark Stars from Perturbative QCD
Eduardo S. Fraga, Robert D. Pisarski, Jurgen Schaffner-Bielich
As a model for nonideal behavior in the equation of state of QCD at high density, we consider cold quark matter in perturbation theory. To second order in the strong coupling const…
