Structured beam controlled super-resolution in quantum dots via rapid adiabatic passage
Partha Das, Samit Kumar Hazra, Tarak Nath Dey
We theoretically investigate rapid adiabatic passage (RAP) based super-resolution microscopy in a two-level quantum dot (QD) system. The system consists of a QD interacting with tw…

A comparative study of focusing with scalar and vector beams in an active Raman gain system
Partha Das, Tarak Nath Dey
We investigate the focusing characteristics of scalar and vector beams within an atomic medium. An active-Raman-gain configuration is employed to achieve significant Kerr nonlinear…
