Pole-Based Approximation of the Fermi-Dirac Function∗∗∗∗
Two approaches for the efficient rational approximation of the Fermi-Dirac function are discussed: one uses the contour integral representation and conformal mapping, and the other is based on a version of the multipole representation of the Fermi-Dirac function that uses only simple poles. Both representations have logarithmic computational complexity. They are of great interest for electronic...

متن کاملGeneralized 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-...
متن کاملFermi-Dirac Statistics
Fermi-Dirac statistics are one of two kinds of statistics exhibited by!identical quantum particles, the other being !Bose-Einstein statistics. Such particles are called fermions and bosons respectively (the terminology is due to Dirac [1902-1984] [1]). In the light of the !spin-statistics theorem, and consistent with observation, fermions are invariably spinors (of half-integral spin), whilst b...
متن کاملBeyond the Pole Approximation
We present a calculation of the complete electroweak O(α) corrections to p p (−) → W ± → ℓ ± νX (ℓ = e, µ) in the Standard Model of electroweak interactions , focusing on those corrections which do not contribute in the pole approximation. We study in detail the effect of these corrections on the transverse mass distribution, the W-width measurement, and the transverse mass ratio and cross sect...
