Phase properties of operator valued measures in phase space
T. Subeesh, Vivishek Sudhir
The Wigner Phase Operator (WPO) is identified as an operator valued measure (OVM) and its eigen states are obtained. An operator satisfying the canonical commutation relation with…

Effect of Squeezing on the Atomic and the Entanglement Dynamics in the Jaynes-Cummings Model
T. Subeesh, Vivishek Sudhir, A. B. M. Ahmed +1
The dynamics of the Jaynes-Cummings interaction of a two-level atom interacting with a single mode of the radiation field is investigated, as the state of the field is gradually ch…

Critical behavior in ultra-strong-coupled oscillators
Vivishek Sudhir, Marco G. Genoni, Jinhyoung Lee +1
We investigate the strong coupling regime of a linear - coupled harmonic oscillator system, by performing a direct diagonalization of the hamiltonian. It is shown that the $x…
