Realizing negative index of refraction in an ensemble of ground-state polar molecules with lasers
Dibyendu Sardar, Sauvik Roy, Ghanasyam Remesh +2
We propose a coherent optical method for creating negative refractive index (NRI) for a gaseous ensemble of ground-state polar molecules possessing both permanent electric and magn…
Modeling atom-atom interactions at low energy by Jost-Kohn potentials
Subhanka Mal, Kingshuk Adhikary, Dibyendu Sardar +2
More than 65 years ago, Jost and Kohn [R. Jost and W. Kohn, {Phys. Rev.} {\bf 87}, 977 (1952)] derived an explicit expression for a class of short-range model potentials from a giv…
Suppressing deleterious effects of spontaneous emission in creating bound states in cold atom continuum
Somnath Naskar, Dibyendu Sardar, Bimalendu Deb +1
In a previous paper [B. Deb and G. S. Agarwal, Phys. Rev. A 90, 063417 (2014)], it was theoretically shown that, magneto-optical manipulation of low energy scattering resonances an…
Spectroscopic properties of the molecular ions BeX^+ (X=Na, K, Rb): Forming cold molecular ions from an ion-atom mixture by stimulated Raman adiabatic process
Hela Ladjimi, Dibyendu Sardar, Mohamed Farjallah +5
In this theoretical work, we calculate potential energy curves, spectroscopic pa- rameters and transition dipole moments of molecular ions BeX^+ (X=Na, K, Rb) composed of alkaline…
