Shape Invariant Potentials in Higher Dimensions
R. Sandhya, S. Sree Ranjani, A. K. Kapoor
In this paper we investigate the shape invariance property of a potential in one dimension. We show that a simple ansatz allows us to reconstruct all the known shape invariant pote…
Eigenvalue statistics for the sum of two complex Wishart matrices
Santosh Kumar
The sum of independent Wishart matrices, taken from distributions with unequal covariance matrices, plays a crucial role in multivariate statistics, and has applications in the fie…
Admissible fundamental operators
Tirthankar Bhattacharyya, Sneh Lata, Haripada Sau
Let and be two bounded operators on two Hilbert spaces. Let their numerical radii be no greater than one. This note investigate when there is a -contraction such…
Mapping generalized Jaynes-Cummings interaction into correlated finite-sized systems
Himadri Shekhar Dhar, Arpita Chatterjee, Rupamanjari Ghosh
We consider a generalized Jaynes-Cummings model of a two-level atom interacting with a multimode nondegenerate coherent field. The sum of the mode frequencies is equal to the two-l…
