S-parameter at Non-Zero Temperature and Chemical Potential [PDF]

, 2011
We compute the finite-temperature and matter density corrections to the S-parameter at the one-loop level. At nonzero temperature T and matter density {mu} Lorentz symmetry breaks and therefore we suggest a suitable generalization of the S-parameter.

Three flavour Quark matter in chiral colour dielectric model [PDF]

, 1995
We investigate the properties of quark matter at finite density and temperature using the nonlinear chiral extension of Colour Dielectric Model (CCM).

Chiral And Parity Anomalies At Finite Temperature And Density [PDF]

, 1997
Two closely related topological phenomena are studied at finite density and temperature. These are chiral anomaly and Chern-Simons term. By using different methods it is shown that $\mu^2 = m^2$ is the crucial point for Chern-Simons at zero temperature ...

Stabilizing complex Langevin for real-time gauge theories with an anisotropic kernel

Journal of High Energy Physics, 2023
The complex Langevin (CL) method is a promising approach to overcome the sign problem that occurs in real-time formulations of quantum field theories. Using the Schwinger-Keldysh formalism, we study SU(N c ) gauge theories with CL.

Evidence for BCS Diquark Condensation in the 3+1d Lattice NJL Model [PDF]

, 2002
We present results of numerical simulations of the 3+1d Nambu - Jona-Lasinio model with a non-zero baryon chemical potential mu, with particular emphasis on the superfluid diquark condensate and associated susceptibilities. The results, when extrapolated

Fate of the topological susceptibility in two-color dense QCD

Journal of High Energy Physics, 2023
We explore the topological susceptibility at finite quark chemical potential and zero temperature in two-color QCD (QC2D) with two flavors. Through the Ward-Takahashi identities of QC2D, we find that the topological susceptibility in the vacuum solely ...

θ dependence of T c in 4d SU(3) Yang-Mills theory with histogram method and the Lee-Yang zeros in the large N limit

Journal of High Energy Physics, 2022
The phase diagram on the θ-T plane in four dimensional SU(3) Yang-Mills theory is explored. We revisit the θ dependence of the deconfinement transition temperature, T c (θ), on the lattice through the constraint effective potential for Polyakov loop. The

Influence for Ambient Relative Humidity and Pollution on Infrared Detection of Zero Resistance Insulators

Frontiers in Energy Research, 2022
Porcelain insulators play a vital role for the safety and stability operations of electric systems. In a strong electric field, these insulators easily break down and become zero resistance insulators, which impacts the safety and stability operations of

Criticality from Einstein-Maxwell-dilaton holography at finite temperature and density

, 2020
We investigate consistent charged black hole solutions to the Einstein-Maxwell-Dilaton (EMD) equations that are asymptotically AdS. The solutions are gravity duals to phases of a non-conformal plasma at finite temperature and density.

Pion screening mass at finite chemical potential

Journal of High Energy Physics, 2023
We present a method to compute the responses of meson screening masses to the chemical potential by Taylor expanding the correlator using lattice QCD simulation. We start by comparing the free theory lattice results with the analytical expression.
