Photon-mediated thermodynamics and density fluctuations in an ensemble of laser-cooled Cesium atoms
Arnab Ghosh, Inderpreet Kaur, Hemant Yadav +5
We present an experimental study of detuning-dependent properties of a laser-cooled cesium cloud in a magneto-optical trap. Fluorescence images are used to extract the cloud size,…
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…
Quantum thermal machine regimes in the transverse-field Ising model
Vishnu Muraleedharan Sajitha, Bodhaditya Santra, Matthew J. Davis +1
We identify and interpret the possible quantum thermal machine regimes with a transverse-field Ising model as the working substance. In general, understanding the emergence of such…
Generating discrete time crystals through optimal control
Mrutyunjaya Sahoo, Rahul Ghosh, Bandita Das +3
In this work we use optimal control to generate Discrete Time Crystals (DTC) in generic many-body quantum systems. We define appropriate cost functions, which, when optimized, resu…
