Siamak Khademi
Wigner distribution function has much importance in quantum statistical mechanics. It finds applications in various disciplines of physics including condense matter, quantum optics…
Operator Gauge Symmetry in QED
Siamak Khademi, Sadollah Nasiri
In this paper, operator gauge transformation, first introduced by Kobe, is applied to Maxwell's equations and continuity equation in QED. The gauge invariance is satisfied after qu…
A Generalized Rule For Non-Commuting Operators in Extended Phase Space
S. Nasiri, S. Khademi, S. Bahrami +1
A generalized quantum distribution function is introduced. The corresponding ordering rule for non-commuting operators is given in terms of a single parameter. The origin of this p…
