Study of Rydberg blockade in thermal vapor
Arup Bhowmick, Dushmanta Kara, Ashok K. Mohapatra
We present the experimental demonstration of Rydberg blockade in thermal atomic vapor where the atoms are not necessarily be frozen. We show that not all the interacting atoms but…

Rydberg interaction induced enhanced excitation in thermal atomic vapor
Dushmanta Kara, Arup Bhowmick, Ashok K. Mohapatra
We present the experimental demonstration of interaction induced enhancement in Rydberg excitation or Rydberg anti-blockade in thermal atomic vapor. We have used optical heterodyne…

Study of Rydberg blockade mediated optical non-linearity in thermal vapor using optical heterodyne detection technique
Arup Bhowmick, Dushmanta Kara, Ashok K. Mohapatra
We demonstrate the phenomenon of blockade in two-photon excitations to the Rydberg state in thermal vapor. A technique based on optical heterodyne is used to measure the dispersion…
