Low Temperature Properties of the Fermi-Dirac, Boltzman and Bose-Einstein Equations

چکیده

We investigate low temperature (T ) properties of three classical quantum statistics models: (I) the Fermi-Dirac equation, (II) the Boltzman equation, and (III) the Bose-Einstein equation. It is widely assumed that each of these equations is valid for all T > 0. For each equation we prove that this assumption leads to erroneous predictions as T → 0. Our approach to correct these errors gives new low temperature predictions which contradict previous theory. We examine a two state paramagnetism system and show how our new low temperature prediction compares favorably with experimental data.

آرام کردن مایع فرمی: جدال با علامتهای فرمیونی غیر مستقیم

 The fermion sign problem is studied in the path integral formalism. The standard picture of Fermi liquids is first critically analyzed, pointing out some of its rather peculiar properties. The insightful work of Ceperley in constructing fermionic path integrals in terms of constrained world-lines is then reviewed. In this representation, the minus signs associated with Fermi-Dirac statistics a...

Generalized Bose-Einstein and Fermi-Dirac distributions: The interpolation approximation

Generalized Bose-Einstein and Femi-Dirac distributions in the interpolation approximation (IA) has been shown to yield results in agreement with the exact ones within the O(q − 1) and in highand low-temperature limits [H. Hasegawa, arXiv:0904.2399], where q stands for the entropic index. We have applied the generalized distributions in the IA to typical nonextensive quantum subjects: the black-...

Path integral molecular dynamics for Bose-Einstein and Fermi-Dirac statistics

We propose a promising extension of the path integral molecular dynamics method to Bose-Einstein and Fermi-Dirac statistics. The partition function for the quantum statistics was re-written in a form amenable to the molecular dynamics method with the aid of an idea of pseudopotential for the permutation of particles. Our pseudopotential is a rigorous one describing the whole effect of Bose-Eins...

Bose-Einstein and Fermi-Dirac distributions in nonextensive quantum statistics: An exact approach

Bose-Einstein (BE) and Fermi-Dirac (FD) distributions in nonextensive quantum statistics have been discussed with the use of exact integral representations for the grand canonical partition function [Rajagopal, Mendes and Lenzi, Phys. Rev. Lett. 80, 3907 (1998)]. Integrals along real axis in the case of q > 1.0 are modified by an appropriate change of variable, which makes numerical calculation...

Operator Representation of Fermi-Dirac and Bose-Einstein Integral Functions with Applications

Fermi-Dirac and Bose-Einstein functions arise as quantum statistical distributions. The Riemann zeta function and its extension, the polylogarithm function, arise in the theory of numbers. Though it might not have been expected, these two sets of functions belong to a wider class of functions whose members have operator representations. In particular, we show that the Fermi-Dirac and Bose-Einst...
