Thermodynamic instabilities in holographic neutron stars at finite temperature
(IOP Publishing, 2020-08)
We study the thermodynamics of a self-gravitating system of neutral fermions at finite temperature and analyze its backreaction in an asymptotically AdS space. We evaluate numerically the free entropy as a function of ...
Coulomb gauge quark model, vacuum condensates and high density quark matter
(American Institute of Physics (AIP), 2002-01-01)
We consider here a Coulomb gauge quark model which includes an explicit construct for a nontrivial vacuum structure in QCD at finite density. Non-perturbative renormalization of ultraviolet diverges is performed by adding ...
Lorentz-violating effects in three-dimensional QED
(World Scientific Publ Co Pte Ltd, 2014-09-10)
Inspired in discussions presented lately regarding Lorentz-violating interaction terms in B. Charneski, M. Gomes, R. V. Maluf and A. J. da Silva, Phys. Rev. D 86, 045003 (2012); R. Casana, M. M. Ferreira Jr., R. V. Maluf ...
Comparison between the continuum threshold and the Polyakov loop as deconfinement order parameters
(2017)
We study the relation between the continuum threshold s(0) within finite energy sum rules and the trace of the Polyakov loop Phi in the framework of a nonlocal SU(2) chiral quark model, establishing a contact between both ...
On the asymptotic behavior of effective QED at finite temperature

Spin-charge coupling in quantum wires at zero magnetic field
(AMER PHYSICAL SOC, 2010)
We discuss an approximation for the dynamic charge response of nonlinear spin-1/2 Luttinger liquids in the limit of small momentum. Besides accounting for the broadening of the charge peak due to two-holon excitations, the ...
