Nonlinear displaced Kerr state and its nonclassical properties
Arpita Chatterjee, Rupamanjari Ghosh
We construct a distinct class of nonlinear displaced Kerr state by application of the displacement operator upon a state which is prepared by sending the well-known photon-added co…
A pedestrian introduction to coherent and squeezed states
Bijan Bagchi, Rupamanjari Ghosh, Avinash Khare
This review is intended for readers who want to have a quick understanding on the theoretical underpinnings of coherent states and squeezed states which are conventionally generate…
Coherent Population Oscillation-Based Light Storage
P. Neveu, M. -A. Maynard, R. Bouchez +5
We theoretically study the propagation and storage of a classical field in a -type atomic medium using coherent population oscillations (CPOs). We show that the propagation eige…
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…
Generating continuous variable entangled states for quantum teleportation using a superposition of number-conserving operations
Himadri Shekhar Dhar, Arpita Chatterjee, Rupamanjari Ghosh
We investigate the states generated in continuous variable (CV) optical fields on operating them with a number-conserving operator of the type $s\hat{a}\hat{a}^†+ t\hat{a}^†\hat{a}…
Cumulative quantum work-deficit versus entanglement in the dynamics of an infinite spin chain
Himadri Shekhar Dhar, Rupamanjari Ghosh, Aditi Sen De +1
We find that the dynamical phase transition (DPT) in nearest-neighbor bipartite entanglement of time-evolved states of the anisotropic infinite quantum XY spin chain, in a transver…
