Decoupling of quark condensate from the effective nucleon mass at high density (ϱ) and temperature (T)
(1995-11-16)
It is found that the quark condensate 〈qq〉, instead of decreasing at high ρ{variant}, as commonly expected, starts to increase after a certain density (∼ 1.5ρ{variant}0 - in standard relativistic nuclear matter models. ...
On the asymptotic behavior of effective QED at finite temperature
(Springer, 2003-11-01)
The aim of this paper is to study finite temperature effects in effective quantum electrodynamics using Weisskopf's zero-point energy method in the context of thermo, field dynamics. After a general calculation for a weak ...
Helium in polygonal nanopores at zero temperature: Density functional theory calculations
(American Physical Society, 2008-12)
We investigate adsorption of helium in nanoscopic polygonal pores at zero temperature using a finite-range density functional theory. The adsorption potential is computed by means of a technique denoted as the elementary ...

Fluid helium in a narrow pore at zero temperature
(Springer/Plenum Publishers, 2011-02)
The zero temperature adsorption isotherm of 4He in a rigid cylindrical pore with alkali metal walls is computed within finite-range density functional theory, with the radius of the tube as a parameter. It is shown that ...

Comparison between the continuum threshold and the Polyakov loop as deconfinement order parameters
(American Physical Society, 2017-02)
We study the relation between the continuum threshold s0 within finite energy sum rules and the trace of the Polyakov loop Φ in the framework of a nonlocal SU(2) chiral quark model, establishing a contact between both ...
