Geometric phase for mixed states: a differential geometric approach

S. Chaturvedi, E. Ercolessi, G. Marmo +3

A new definition and interpretation of geometric phase for mixed state cyclic unitary evolution in quantum mechanics are presented. The pure state case is formulated in a framework…

Local cloning of Bell states and distillable entanglement

Sibasish Ghosh, Guruprasad Kar, Anirban Roy

The necessary and sufficient amount of entanglement required for cloning of orthogonal Bell states by local operation and classical communication is derived, and using this result,…

Geometric Phase in a Bose-Einstein Josephson Junction

Radha Balakrishnan, Mitaxi Mehta

We calculate the geometric phase associated with the time evolution of the wave function of a Bose-Einstein condensate system in a double-well trap by using a model for tunneling b…

Wigner distributions for non Abelian finite groups of odd order

N. Mukunda, S. Chaturvedi, R. Simon

Wigner distributions for quantum mechanical systems whose configuration space is a finite group of odd order are defined so that they correctly reproduce the marginals and have des…

Wigner distributions and quantum mechanics on Lie groups: the case of the regular representation

N. Mukunda, Arvind, S. Chaturvedi +1

We consider the problem of setting up the Wigner distribution for states of a quantum system whose configuration space is a Lie group. The basic properties of Wigner distributions…
