Structured-Light Magnetometry in a Coherently Controlled Atomic Medium
Parkhi Bhardwaj, Shubhrangshu Dasgupta
A structured-light-based approach to magneto-optical rotation (MOR) magnetometry is proposed, in which magnetically induced polarization rotation is converted into a directly obser…

Gain-Assisted and Dynamically Controlled Optical Bistability for Quantum Logic Gate Applications
Parkhi Bhardwaj, Poonam Yadav, Bodhaditya Santra +1
The propagation of a probe field in an N-type four level cold atomic system is investigated under the influence of multiple coherent fields. Coherent control of quantum interferenc…

Generation of Structured Light and Controlled-NOT Gate in Microwave Regime
Parkhi Bhardwaj, Shubhrangshu Dasgupta
In this work, we propose a theoretical model for generating microwave beams with non-zero orbital angular momentum utilizing the atomic vapor medium combined with coherent control…
