Quantum entanglement in the SU(1,1)-related coherent fields interacting with a moving atom

Liao, Xiang-Ping; Fang, Mao-Fa; Zhou, Qing-Ping - In: Physica A: Statistical Mechanics and its Applications 365 (2006) 2, pp. 351-359

The entanglement properties of the SU(1,1)-related coherent fields interacting with a moving atom via the two-photon transition are investigated. We discuss the quantum entanglement between the SU(1,1)-related coherent fields and the moving atom by using the quantum reduced entropy and that...

Fixation probability and the crossing time in the Wright–Fisher multiple alleles model

Gill, Wonpyong - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 15, pp. 3124-3132

The fixation probability and crossing time in the Wright–Fisher multiple alleles model, which describes a finite haploid population, were calculated by switching on an asymmetric sharply-peaked landscape with a positive asymmetric parameter, r, such that the reversal allele of the optimal...

Fa-Yueh Wu's contributions in physics

Maillard, J.-M. - In: Physica A: Statistical Mechanics and its Applications 321 (2003) 1, pp. 28-44

We sketch a subset of Professor F.Y. Wu's contributions in lattice statistical mechanics, solid state physics, graph theory, enumerative combinatorics and other domains of physics and mathematics. We will recall some of F.Y. Wu's most important and well-known classic results and we will also...

Generalized thermostatistics based on deformed exponential and logarithmic functions

Naudts, Jan - In: Physica A: Statistical Mechanics and its Applications 340 (2004) 1, pp. 32-40

The equipartition theorem states that inverse temperature equals the log-derivative of the density of states. This relation can be generalized by introducing a proportionality factor involving an increasing positive function φ(x). It is shown that this assumption leads to an equilibrium...

Duality and spatial inhomogeneity

Piasecki, R; Plastino, A - In: Physica A: Statistical Mechanics and its Applications 305 (2002) 1, pp. 113-118

Within the framework on non-extensive thermostatistics we revisit the recently advanced q-duality concept. We focus our … measure exhibits a generalised duality that links appropriate pairs of q and q′ values. The simplest q↔q′ invariant function … value at q0, this invariant function accurately approximates the investigated q-measure, nitidly evidencing the duality …
