Substantiation of Thermodynamic Criteria of Explosion Safety in Process of Severe Accidents in Pressure Vessel Reactors
severe accident hydrogenous steam-air mixture fuel-containing masses steam-gas explosion criteria model
2012/4/19
The paper represents original development of thermodynamic criteria of occurrence conditions of steam-gas explosions in the process of severe accidents. The received results can be used for modelling ...
Thermodynamic phase transitions and shock singularities

2011/9/29
Abstract: We show that under rather general assumptions on the form of the entropy function, the energy balance equation for a system in thermodynamic equilibrium is equivalent to a set of nonlinear e...
Thermodynamic Geometry, Phase Transitions, and the Widom Line
Thermodynamic Geometry Phase Transitions the Widom Line
2011/9/13
We construct a novel approach, based on thermodynamic geometry, to characterize first-order phase transitions from a microscopic perspective,through the scalar curvature in the equilibrium thermodynam...

2010/11/23
It is known that itinerant metamagnetic transitions can be driven by features in the electronic
density of states. We study the signatures of these transitions in the entropy and speci c heat for a v...

2010/11/23
The thermodynamic and kinetic properties of hydrogen adatoms on graphene are important to the materials and devices based on hydrogenated graphene. Hydrogen dimers on graphene with coverages varying f...
Comparison of Thermodynamic Characteristics in Quantum and Classical Approaches and Game Theory
Comparison Thermodynamic Characteristics Quantum Classical Approaches Game Theory
2010/11/11
We fix the temperature $T$ and consider mean energy and entropy as two players of a game. As a result, basic formulas for the quantum mean energy and the quantum entropy are derived. We compare also t...

2011/9/8
There has recently been a good deal of controversy about Landauer's Principle, which is often stated as follows: The erasure of one bit of information in a computational device is necessarily accompan...
We study quantum fidelity, the overlap between two ground states of a many-body system, focusing on the thermodynamic regime. We present novel analytical results for quantum fidelity of the Ising chai...
