Money has a material counterpart, such as banknotes or coins, and an ideal expression, monetary units. In the latter case, it is boson-like: individual incomes have no a priori limit, and their units are not distinguishable from each other in economi

The relations between information, entropy and energy, which are well known in equilibrium thermodynamics, are not clear far from equilibrium. Moreover, the usual expression of the classical thermodynamic potentials is only valid near equilibrium. In

It is a general belief that in some early stages of the evolution of the Universe unequilibrium situations played important role. In order to incorporate some deviations from thermal equilibrium into the description of the evolution, here an extensio

Characterizing the energetic, electric and magnetic interactions occurring at the superconductivity by means of the method of extensive and intensive parameters, the total entropy density of a general superconductor has been determined. The resulting

The fact that the energy-momentum tensor has nonzero vacuum expectation value in some space-times (the so-called back reaction) indicates a nontrivial thermodynamics of such vacua. A consequent thermodynamic analysis of the problem in Robertson-Walke

The phase transition “type I to type II superconductivity” was investigated theoretically by thermodynamic methods in the framework of the GLAG formalism. The conditions of the forming of the vortex lattice structure were determined and the featu

In a one dimensional model the possibility of synchronization of the flux line system to the randomly distributed pinning centres is shown. The result yields direct summation without threshold in the very dilute case.

Thermodynamic description of the superconducting states has been performed. The thermodynamic interactions and the extensive and intensive parameters are determined. It is shown that the use of magnetic moment as an extensive parameter results in a c

Because of nuclear transparency at beam energies relevant to quark plasma formation, the extension of phase equilibrium conditions for interpenetrating pieces of matter is investigated. Applying this thermodynamical formalism to the deconfinement tra

The postulate system proposed byCallen is not complete, as it does not yield a unique entropy function. The necessary and sufficient additions to define the unique entropy function are determined.
