Finite temperature gluon propagator in Landau gauge: non-zero Matsubara frequencies and spectral densities [PDF]
EPJ Web of Conferences, 2018 We report on the lattice computation of the Landau gauge gluon propagator at finite temperature, including the non-zero Matsubara frequencies. Moreover, the corresponding Källén-Lehmann spectral density is computed, using a Tikhonov regularisation together with the Morozov discrepancy principle. Implications for gluon confinement are also discussed.

A continuum model of gas flows with localized density variations [PDF]
, 2008 We discuss the kinetic representation of gases and the derivation of macroscopic equations governing the thermomechanical behavior of a dilute gas viewed at the macroscopic level as a continuous medium.

The sphaleron rate from 4D Euclidean lattices
Journal of High Energy Physics, 2023 We develop a new method to determine thermal activation rates, such as for bubble nucleation, topology change, etc., using 4-dimensional Euclidean methods. This allows nonperturbative study on the lattice. We then investigate the strong sphaleron rate in

The Staggered Fermion for the Gross-Neveu Model at Non-Zero Temperature and Density
Journal of Modern Physics, 2021 The 2+1d Gross-Neveu model with finite density and finite temperature are studied by the staggered fermion discretization. The kinetic part of this staggered fermion in momentum space is used to build the relation between the staggered fermion and Wilson-like fermion.

Properties of kaon at non-zero temperature and baryon chemical potential [PDF]
, 2023 We investigate the spectroscopic properties of the strange particle kaon in the framework of hot and dense QCD. To this end, first, we find the perturbative spectral density, which is connected with both the temperature $T$ and the baryon chemical ...

Low temperature transport and evidence for nuclear order in GaAs Quantum Wires [PDF]
, 2014 In this thesis we focus on low temperature transport through cleaved edge overgrowth (CEO) quantum wires. This thesis is motivated by recent theoretical work on one hand that predicts the formation of a nuclear helimagnet in presence of a Luttinger ...

Chiral symmetry restoration in the three-dimensional four-fermion model at nonzero temperature and density [PDF]
Physical Review D, 2001 The three-dimensional four-fermion model with a Z_2 chiral symmetry and N=4 fermion species in the system is investigated numerically at non-zero temparature and chemical potential. The phase diagram in the (chemical potential, temperature) plane is mapped out quantitatively.

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.
