Wigner-Weyl isomorphism for quantum mechanics on Lie groups
N. Mukunda, G. Marmo, Alessandro Zampini +2
The Wigner-Weyl isomorphism for quantum mechanics on a compact simple Lie group is developed in detail. Several New features are shown to arise which have no counterparts in th…
A New Relation between post and pre-optimal measurement states
Chirag Dhara, N. D. Hari Dass
When an optimal measurement is made on a qubit and what we call an Unbiased Mixture of the resulting ensembles is taken, then the post measurement density matrix is shown to be rel…
q-Fermionic Numbers and Their Roles in Some Physical Problems
R. Parthasarathy
The q-fermion numbers emerging from the q-fermion oscillator algebra are used to reproduce the q-fermionic Stirling and Bell numbers. New recurrence relations for the expansion coe…
Locally Accessible Information and Distillation of Entanglement
Sibasish Ghosh, Pramod Joag, Guruprasad Kar +2
A new type of complementary relation is found between locally accessible information and final average entanglement for given ensemble. It is also shown that in some well known dis…
