Parity-time-symmetric closed form optical quadrimer waveguides
Samit Kumar Gupta, Amarendra K. Sarma
A closed form PT symmetric quadrimer optical waveguide structure, reminiscent of the four-state quantum system found in quantum optics, is studied. The beam dynamics of the structu…

Simultaneous control of optical dipole force and coherence creation by super-Gaussian femtosecond pulses in lambda-like atomic systems
Pawan Kumar, Parvendra Kumar, Amarendra K. Sarma
We report a study on the optical dipole force on a beam of neutral three-level like atomic system induced by a femtosecond super-Gaussian pulse. We show that maximum coherence betw…
