J1432+158: the most distant giant quasar
A. K. Singal, C. Konar, D. J. Saikia
We present low-frequency, GMRT (Giant Metrewave Radio Telescope) observations at 333 and 617 MHz of the most-distant giant quasar, J1432+158, which is at a redshift of 1.005. The r…
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…
Constraints on flavour-dependent long-range forces from atmospheric neutrino observations at Super-Kamiokande
Anjan S. Joshipura, Subhendra Mohanty
In the minimal standard model it is possible to gauge any one of the following global symmetries in an anomaly free way: (i), (ii) or (iii) . If the…
