Equation of state and phase diagram of tin at high pressures

open access: yes, 2008
A thermodynamic model of the free energy as a function of volume and temperature for tin with taking into account the polymorphic transformation and melting effects is proposed.

Finite-temperature Dicke phase transition and the collapse of superradiant phase in an optomechanical-atomic cavity

open access: yesResults in Physics, 2021
We mainly investigate Dicke phase transition at finite temperature in an optomechanical-atomic cavity by means of the functional path-integral approach. By the thermodynamic equilibrium equation, the mean photon number, the scaled atomic population, the ...

Finite temperature phase diagram of a spin-polarized ultracold Fermi gas in a highly elongated harmonic trap [PDF]

open access: yes, 2008
We investigate the finite temperature properties of an ultracold atomic Fermi gas with spin population imbalance in a highly elongated harmonic trap.

Quantum computation in fermionic thermal field theories

open access: yesJournal of High Energy Physics
Thermal properties of quantum fields at finite temperature are crucial to understanding strongly interacting matter and recent development in quantum computing has provided an alternative and promising avenue of study.

Ultracold bosons in a synthetic periodic magnetic field: Mott phases and re-entrant superfluid-insulator transitions [PDF]

open access: yes, 2010
We study Mott phases and superfluid-insulator (SI) transitions of ultracold bosonic atoms in a two-dimensional square optical lattice at commensurate filling and in the presence of a synthetic periodic vector potential characterized by a strength $p$ and

Quark flavors in hot and dense holographic QCD: setup and comparison to data

open access: yesJournal of High Energy Physics
We establish a flavor dependent holographic framework for hot and dense QCD. To this end, we generalize a class of bottom-up holographic models for QCD in the Veneziano limit (V-QCD) by incorporating explicit flavor dependence. Specifically, we develop a

Lattice QCD Constraints on the Nuclear Equation of State

open access: yes, 2006
Based on the quasi-particle description of the QCD medium at finite temperature and density we formulate the phenomenological model for the equation of state that exhibits crossover or the first order deconfinement phase transition.

Localized States in Periodically Forced Systems [PDF]

open access: yes, 2015
The theory of stationary spatially localized patterns in dissipative systems driven by time-independent forcing is well developed. With time-periodic forcing, related but time-dependent structures may result.

Thermal pion condensation: holography meets lattice QCD

open access: yesJournal of High Energy Physics
The holographic Witten-Sakai-Sugimoto model is often employed to describe strongly-coupled baryonic and isospin-asymmetric matter, for example in the context of neutron stars.

Challenges in QCD matter physics - The Compressed Baryonic Matter experiment at FAIR

open access: yes, 2017
Substantial experimental and theoretical efforts worldwide are devoted to explore the phase diagram of strongly interacting matter. At LHC and top RHIC energies, QCD matter is studied at very high temperatures and nearly vanishing net-baryon densities ...
