Observation of false vacuum decay via bubble formation in ferromagnetic superfluids
Alessandro Zenesini, Anna Berti, Riccardo Cominotti +7
In quantum field theory, the decay of an extended metastable state into the real ground state is known as ``false vacuum decay'' and it takes place via the nucleation of spatially…
Scale independence in an asymptotically free theory at finite temperatures
Gabriel N. Ferrari
A recently developed variational resummation technique incorporating renormalization group properties has been shown to solve the scale dependence problem that plagues the evaluati…
Asymptotically Free Theory with Scale Invariant Thermodynamics
Gabriel N. Ferrari, Jean-Loic Kneur, Marcus B. Pinto +1
A recently developed variational resummation technique, incorporating renormalization group properties consistently, has been shown to solve the scale dependence problem that plagu…
Dynamical Generation of a Repulsive Vector Contribution to the Quark Pressure
Tulio E. Restrepo, Juan Camilo Macias, Marcus Benghi Pinto +1
Lattice QCD results for the coefficient appearing in the Taylor expansion of the pressure show that this quantity raises with the temperature towards the Stefan-Boltzmann lim…
Chiral Transition Within Effective Quark Models Under Magnetic Fields
Gabriel N. Ferrari, Andre F. Garcia, Marcus B. Pinto
We consider the simplest versions of the Nambu--Jona-Lasinio (NJL) model and the Linear Sigma Model (LSM), in the Mean Field Approximation (MFA), in order to analyze hot and dense…
