Statistical aspects of harmonic oscillator under minimal length supposition
Farhang Matin, L.; Miraboutalebi, S. - In: Physica A: Statistical Mechanics and its Applications 425 (2015) C, pp. 10-17
This paper attempts to study the influence of the Generalized Uncertainty Principle (GUP) on the statistical aspects of the N-one dimensional harmonic oscillator. The Investigations are introduced in both classical and quantum domains. It is shown how the GUP scenario modifies the N-oscillator...

Yang–Lee circle theorem for an ideal pseudospin-1/2 Bose gas in an arbitrary external potential and in an external magnetic field
Wang, Xian-Zhi - In: Physica A: Statistical Mechanics and its Applications 380 (2007) C, pp. 163-171
Yang–Lee circle theorem was extended to an ideal homogeneous pseudospin-1/2 Bose gas in an external magnetic field [X.Z. Wang, Phys. Rev. E 63 (2001) 046103]. In this paper, the theorem is extended to the case with an arbitrary external potential. The densities of zeros for several cases are...

Critical temperature of Bose–Einstein condensation of a dilute Bose gas
Wang, Xian-Zhi - In: Physica A: Statistical Mechanics and its Applications 341 (2004) C, pp. 433-443
Using the Huang–Yang–Luttinger and Lee–Yang virial expansions of a dilute Bose gas as well as our theory of phase transition, we show that in the dilute limit, the critical temperature of Bose–Einstein condensation of a Bose gas is given by [Tc−Tc(0)]/Tc(0)=γn1/3a,...
