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…
DC field induced enhancement and inhibition of spontaneous emission in a cavity
G. S. Agarwal, P. K. Pathak
We demonstrate how spontaneous emission in a cavity can be controlled by the application of a dc field. The method is specially suitable for Rydberg atoms. We present a simple argu…
Mesoscopic Superposition of States with Sub-Planck Structures in Phase Space
G. S. Agarwal, P. K. Pathak
We propose a method using the dispersive interaction between atoms and a high quality cavity to realize the mesoscopic superposition of coherent states which would exhibit sub-Plan…
Preparation of W, GHZ, and two-qutrit states using bimodal cavities
Asoka Biswas, G. S. Agarwal
We show how one can prepare three-qubit entangled states like W states, Greenberger-Horne-Zeilinger states as well as two-qutrit entangled states using the multiatom two-mode entan…
Slow Light in Doppler Broadened Two level Systems
G. S. Agarwal, Tarak Nath Dey
We show that the propagation of light in a Doppler broadened medium can be slowed down considerably eventhough such medium exhibits very flat dispersion. The slowing down is achiev…
Model study on the photoassociation of a pair of trapped atoms into an ultralong-range molecule
B. Deb, L. You
Using the method of quantum-defect theory, we calculate the ultralong-range molecular vibrational states near the dissociation threshold of a diatomic molecular potential which asy…
