Superfluid mott insulation bose glass monte carlo simulation
2014/12/20
In a recent Letter [1] (see also [2]) the authors presented numerical evidence supporting an idea of a direct transition between the superfluid (SF) and Mott insulating (MI) phases in the disordered B...
Quantum statistics: Is there an effective fermion repulsion or boson attraction?
Fermions and bosons highly misleading quantum statistics
2014/12/20
Physicists often claim that there is an effective repulsion between fermions, implied by the Pauli principle, and a corresponding effective attraction between bosons. We examine the origins and validi...
The "boson polynomials" of Gel'fand basis and the analytic expression of Wigner's coefficients with multiplicity for the canonical basis of unitary groups
Gel'fand basis Wigner's coefficients canonical basis Representation Theory
2011/7/26
Abstract: In this paper we present the generating function method for the derivation of bosons polynomials of Gel'fand basis and Wigner coefficients for the canonical basis of SU(n). We find a new ana...
NNLO Benchmarks for Gauge and Higgs Boson Production at TeV Hadron Colliders
NNLO Benchmarks Gauge Higgs Boson Production TeV Hadron Colliders
2011/1/14
The inclusive production cross sections for W+,W− and Z0-bosons form important bench-marks for the physics at hadron colliders. We perform a detailed comparison of the pre-dictions for these sta...

We introduce higher order polynomial deformations of $A_1$ Lie algebra. We construct their unitary representations and the corresponding single-variable differential operator realizations. We then use...
李超代数B(0,1)的非齐次微分实现,Boson-Fermion实现及其表示
非齐次微分 李超代数
2009/7/10
本文研究了李超代数B(0,1)在非齐次多项式空间上的微分实现(称为非齐次微分实现),和对应的非齐次Boson-Fermion实现.利用非齐次Boson-Fermion实现,在 Heisenberg-Weyl超代数的通用包络代数,其子空间和商空间上研究了B(0,1)的一类新的不可分解表示和不可约表示.B(0,1)的所有有限维不可约表示则作为特殊情况全部给出.

束缚态 Boson 高维Kerr度规
2009/6/1
本文利用分离变量方法得到了在高维Kerr度规中玻色子径向波函数方程,由此讨论了在高维Kerr黑洞周围玻色子的束缚态.结果表明,高维Kerr黑洞与玻色子不能形成量子束缚态,这一结论与玻色子有无质量无关.
A theory of quantum state reduction is advanced. It is based on two principles: (1) Gauge decomposition; (2) Maximum entropy. To wit: (1) The reduction decomposition of a state vector is the Schmidt d...
