We study the equilibrium thermodynamics of a simple, confining, DSE-model of 2-flavour QCD at finite temperature and chemical potential. The model has two phases: one characterised by confinement and dynamical chiral symmetry breaking; and the other by their absence. The phase boundary is defined by the zero of the vacuum-pressure difference between the confined and deconfined phases. Chiral sy...

Abstract The density of states and other thermodynamic functions of helium nanodroplets are calculated for a microcanonical ensemble with both energy and total angular momentum treated as conserved quantum numbers. These functions allow angular momentum conserving evaporative cooling simulations. As part of this project, a recursion relationship is derived for the reduction to irreducible repre...

We analytically calculate some thermodynamic quantities of an ideal g-on gas obeying generalized exclusion statistics. We show that the specific heat of a g-on gas (g 6= 0) vanishes linearly in any dimension as T → 0 when the particle number is conserved and exhibits an interesting dual symmetry that relates the particle-statistics at g to the hole-statistics at 1/g at low temperatures. We deri...

We study the equilibrium thermodynamics of a simple, connning, DSE-model of 2-avour QCD at nite temperature and chemical potential. The model has two phases: one characterised by connnement and dynamical chiral symmetry breaking; and the other by their absence. The phase boundary is deened by the zero of the vacuum-pressure diierence between the connned and deconnned phases. Chiral symmetry res...

By combining thermodynamic database mining with first principles density functional theory and phonon lattice dynamics calculations, a theoretical screening methodology to identify the most promising CO2 sorbent candidates from the vast array of possible solid materials has been proposed and validated. The ab initio thermodynamic technique has the advantage of allowing identification of thermod...

We investigate the equilibrium magnetic properties of a simple cubic small ferromagnetic particle under an external magnetic field. Although the particle is small, it can not be considered as a single-domain unit. The magnetic moments are represented by unitary spin vectors and we consider ferromagnetic interactions between nearest-neighbor spins. The coupling between spins is given in terms of...

We use the virial theorem to derive a closed analytic form of the Helmholtz free energy for a polydisperse system of sticky hard spheres (SHS) within the mean spherical model (MSM). To this end we calculate the free energy of the MSM for an N-component mixture of SHS via the virial route and apply to it-after imposing a Lorentz-Berthelot type rule on the interactions-the stochastic (i.e., polyd...

The thermodynamic free energy F is calculated for a gas whose particles are the quantum excitations of a piecewise uniform bosonic string. The string consists of two parts of length LI and LII , endowed with different tensions and mass densities, adjusted in such a way E-mail address: [email protected] E-mail address: [email protected] that the velocity of sound always equals the velocity of...
