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…
Quantum information entropies of the eigenstates and the coherent state of the Pöschl-Teller potential
Rajneesh Atre, Anil Kumar, C. Nagaraja Kumar +1
The position and momentum space information entropies, of the ground state of the Pöschl-Teller potential, are exactly evaluated and are found to satisfy the bound, obtained by Bec…
Calculation of Band Edge Eigenfunctions and Eigenvalues of Periodic Potentials through the Quantum Hamilton - Jacobi Formalism
S. Sree Ranjani, A. K. Kapoor, P. K. Panigrahi
We obtain the band edge eigenfunctions and the eigenvalues of solvable periodic potentials using the quantum Hamilton - Jacobi formalism. The potentials studied here are the Lam{é}…
Critical fluctuations and entanglement in the nondegenerate parametric oscillator
K. Dechoum, P. D. Drummond, S. Chaturvedi +1
We present a fully quantum mechanical treatment of the nondegenerate optical parametric oscillator both below and near threshold. This is a non-equilibrium quantum system with a cr…
Coherent states for exactly solvable potentials
T. Shreecharan, Prasanta K. Panigrahi, J. Banerji
A general algebraic procedure for constructing coherent states of a wide class of exactly solvable potentials e.g., Morse and P{ö}schl-Teller, is given. The method, {\it a priori},…
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…
