Recently there have been numerous articles on a new relation between entropy and probability which is non-extensive, and which has an undetermined parameter q that depends on the nature of the thermodynamic system under consideration. For q = 1 this relation corresponds to the Boltzmann-Gibbs entropy, but for other values of q it is claimed that this relation leads to a formalism which is also ...

Thermodynamic criticality describes emergent phenomena in a wide variety of complex systems. In the mammalian cortex, one type of complex dynamics that spontaneously emerges from neuronal interactions has been characterized as neuronal avalanches. Several aspects of neuronal avalanches such as their size and life time distributions are described by power laws with unique exponents, indicating a...

We prove the existence, uniqueness, thermodynamic consistency, global boundedness from both above and below, and continuous data dependence for a solution to an integrodifferential model for nonisothermal phase transitions under nonhomogeneous mixed boundary conditions. The specific heat is allowed to depend on the order parameter, and the convex component of the free energy may or may not be s...

The two-phase thermodynamic (2PT) model is generalized to determine the thermodynamic properties of mixtures. In this method, the vibrational density of states (DoS), obtained from the Fourier transform of the velocity autocorrelation function, and quantum statistics are combined to determine the entropy and free energy from the trajectory of a molecular dynamics simulation. In particular, the ...

Recently, a method based on non-equilibrium continuum thermodynamics which derives thermodynamically consistent reaction rate models together with thermodynamic constraints on their parameters was analyzed using a triangular reaction scheme. The scheme was kinetically of the first order. Here, the analysis is further developed for several first and second order schemes to gain a deeper insight ...

Nonlinear properties of the order parameter modulation wave in such systems as thiourea are described in the framework of the phenomenological model with no Lifshitz invariant. It is also shown that for some values of the thermodynamic potential parameters the lock-in transition is continuous in the type II systems. Close to this transition the soliton lattice appears.
