Quantum simulation of chiral phase transitions
Journal of High Energy Physics, 2022 The Nambu–Jona-Lasinio (NJL) model has been widely studied for investigating the chiral phase structure of strongly interacting matter. The study of the thermodynamics of field theories within the framework of Lattice Field Theory is limited by the sign ...

Gluon condensates at finite baryon densities and temperature [PDF]
Zeitschrift f�r Physik C: Particles and Fields, 1993 We derive here the equation of state for quark matter with a nontrivial vacuum structure in QCD at finite temperature and baryon density. Using thermofield dynamics, the parameters of thermal vacuum and the gluon condensate function are determined through minimisation of the thermodynamic potential, along with a self-consistent determination of the ...

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

Friedberg-Lee model at finite temperature and density [PDF]
Physical Review C, 2008 The Friedberg-Lee model is studied at finite temperature and density. By using the finite temperature field theory, the effective potential of the Friedberg-Lee model and the bag constant $B(T)$ and $B(T,μ)$ have been calculated at different temperatures and densities.

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.

Soliton Systems at Finite Temperatures and Finite Densities
, 2002 The finite-density and finite-temperature phase portraits of the baby-Skyrme and Skyrme models are investigated. Both grand-canonical and canonical approaches are employed. The grand-canonical approach can be used to find the ``natural'' crystal structure of the baby-Skyrme model and it is shown to have triangular symmetry.

, 2005 We calculate the density profiles and density correlation functions of the one-dimensional Bose gas in a harmonic trap, using the exact finite-temperature solutions for the uniform case, and applying a local density approximation.

Level-density parameter of nuclei at finite temperature [PDF]
Nuclear Physics A, 1991 Abstract The contribution of particle-particle (hole-hole) and of particle-hole ring diagrams to the nuclear level-density parameter at finite temperature is calculated. We first derive the correlated grand potential with the above ring diagrams included to all orders by way of a finite temperature RPA equation. An expression for the correlated level-

Finite-temperature dynamics of shock waves in an ultracold Fermi gas
, 2018 The study of finite-temperature dynamics of one-dimensional Fermi gases is a challenging problem. These systems can present different phenomena, including the formation and propagation of shock waves and collective oscillations.
