By means of the second derivative of the ground-state energy for a finite-size system method, the quantum phase transitions (QPTs) for the frustrated vertically asymmetric diamond chain (VADC) are investigated. Our results display the plentiful frustration induced quantum phases in the model....

Within the framework of the effective-field theory with correlations, the ferromagnetism of spin-32 Ising model with a transverse crystal field on honeycomb and square and simple cubic lattices is studied. Tricritical phenomena have been observed for the square and simple cubic lattices, but...

We extend the kinetic theory of dilute polyatomic gas mixtures to the case where the particles have various internal energy modes. The present theory is valid when the inernal energy modes are mechanically independent and when the various degrees of freedom of the molecules are at zeroth order...

A methodology was developed to analyze relation-based systems evolving in time by using the fundamental concepts of thermodynamics. The behavior of such systems can be tracked from the scattering matrix which is actually a network of directed vectors (or pathways) connecting subsequent values,...

A simple expression for the first coordination shell of the radial distribution function of the reference hard-sphere fluid is used in combination with Barker–Henderson perturbation theory to obtain the thermodynamic properties of triangular-well fluids. These properties are expressed...

Taking into account the random scatterings due to random eigenfrequencies and random hopping matrices, we obtain the correlation functions for phonon and sound density fluctuations, which yield three and one entropy fluctuation modes at high frequencies, and three and one thermal conductivity at...

In this paper we calculate the constant pressure specific heat response of a water model with a liquid–liquid critical point. We show how, due to the existence of the critical point, there is a secondary maximum in the specific heat at some temperature T*Th for any pressure PPc, being Th the...

The magnetic properties (phase diagram, magnetization curve, spin correlation functions, internal energy and magnetic specific heat) of a decorated ferrimagnetic square lattice composed of three magnetic atoms are investigated on the basis of the differential technique. The system can show many...

We study the thermodynamics of metals by applying q-deformed algebras. We shall mainly focus our attention on q-deformed Sommerfeld parameter as a function of q-deformed electronic specific heat. The results revealed that q-deformation acts as a factor of disorder or impurity, modifying the...

Using Monte Carlo techniques, the two-dimensional site-diluted Ising model is studied. In particular, properties of the specific heat, its critical behaviour and the emergence of a non-singular maximum above the transition temperature at moderate concentration of defects, are discussed.
