The density matrix renormalization group for a quantum spin chain at non-zero temperature [PDF]
Journal of Physics Condensed Matter, 1996 We apply a recent adaptation of White's density matrix renormalisation group (DMRG) method to a simple quantum spin model, the dimerised $XY$ chain, in order to assess the applicabilty of the DMRG to quantum systems at non-zero temperature. We find that very reasonable results can be obtained for the thermodynamic functions down to low temperatures ...

Thermodynamics of two-flavour lattice QCD with an improved Wilson quark action at non-zero temperature and density [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2007 We report the current status of our systematic studies of the QCD thermodynamics by lattice QCD simulations with two flavors of improved Wilson quarks. We evaluate the critical temperature of two flavor QCD in the chiral limit at zero chemical potential and show the preliminary result.

Lattice study on finite density QC2D towards zero temperature
Journal of High Energy PhysicsWe investigate the phase structure and the equation of state (EoS) for dense two-color QCD (QC2D) at low temperature (T = 40 MeV, 324 lattice) for the purpose of extending our previous works [1, 2] at T = 80 MeV (164 lattice).

N-Representable one-electron reduced density matrices reconstruction at non-zero temperatures [PDF]
Acta Crystallographica Section B Structural Science, Crystal Engineering and Materials, 2021 This article retraces different methods that have been explored to account for the atomic thermal motion in the reconstruction of one-electron reduced density matrices from experimental X-ray structure factors (XSF) and directional Compton profiles (DCP).

The four-Fermi model in three dimensions at non-zero density and temperature [PDF]
Nuclear Physics B, 1993 The Four Fermi model with discrete chiral symmetry is studied in three dimensions at non-zero chemical potential and temperature using the Hybrid Monte Carlo algorithm. The number of fermion flavors is chosen large $(N_f=12)$ to compare with analytic results.

Bounding the QCD Equation of State with the Lattice
Journal of High Energy Physics, 2023 The equation of state of QCD matter at high densities is relevant for neutron star structure and for neutron star mergers and has been a focus of recent work.

Pion spectral properties above the chiral crossover of QCD
Journal of High Energy Physics, 2022 Spectral functions encode a wealth of information about the dynamics of any given system, and the determination of their non-perturbative characteristics is a long-standing problem in quantum field theory.
