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…
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…
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…
Dynamics of Ultracold Quantum Gases in the Dissipative Fermi-Hubbard Model
Koen Sponselee, Lukas Freystatzky, Benjamin Abeln +8
We employ metastable ultracold Yb atoms to study dynamics in the 1D dissipative Fermi-Hubbard model experimentally and theoretically, and observe a complete inhibition of t…
Negative differential conductivity in an interacting quantum gas
Ralf Labouvie, Bodhaditya Santra, Simon Heun +2
Negative differential conductivity (NDC) is a widely exploited effect in modern electronic components. Here, a proof-of-principle is given for the observation of NDC in a quantum t…
