Kovacs effects in an aging molecular liquid

open access: yes, 2003
We study by means of molecular dynamics simulations the aging behavior of a molecular model of ortho-terphenyl. We find evidence of a a non-monotonic evolution of the volume during an isothermal-isobaric equilibration process, a phenomenon known in ...

Thermodynamic potentials and Thermodynamic Relations in Nonextensive Thermodynamics

open access: yes, 2010
The generalized Gibbs free energy and enthalpy is derived in the framework of nonextensive thermodynamics by using the so-called physical temperature and the physical pressure.

Gibbs' States for Moser-Calogero Potentials

open access: yes, 1996
We present two independent approaches for computing the thermodynamics for classical particles interacting via the Moser--Calogero potential. Combining the results we propose the form of equation of state or, what is equivalent, the asymptotics of the ...

Collective nature of phonon energies beyond harmonic oscillators

open access: yesComputational Materials Today
Phonon quasi-particles have been monumental in microscopically understanding thermodynamics and transport properties in condensed matter for decades. Phonons have one-to-one correspondence with harmonic eigenstates and their energies are often described ...

Thermodynamics of SU(3) gauge theory at fixed lattice spacing

open access: yes, 2008
We study thermodynamics of SU(3) gauge theory at fixed scales on the lattice, where we vary temperature by changing the temporal lattice size N_t=(Ta_t)^{-1}.

Surface boiling – an “obvious” explanation for the observed limiting temperature of finite nuclei

open access: yesEPJ Web of Conferences, 2012
Limits of stability of nuclear systems are explored within the framework of a finite-range interacting Fermi gas model and microcanonical thermodynamics in Thomas-Fermi approximation.

Classification of complex systems by their sample-space scaling exponents

open access: yesNew Journal of Physics, 2018
The nature of statistics, statistical mechanics and consequently the thermodynamics of stochastic systems is largely determined by how the number of states W ( N ) depends on the size N of the system. Here we propose a scaling expansion of the phasespace
