Coherence, long-range transport and nuclear polarization in a driven-dissipative dark exciton condensate
Amit Jash, Maheswar Swar, Uri Shimon +2
We report direct evidence for macroscopic coherence in a condensate of dark dipolar excitons in coupled quantum wells and show that its formation follows a non-equilibrium, driven-…
Detection of Spin Coherence in Cold Atoms via Faraday Rotation Fluctuations
Maheswar Swar, Dibyendu Roy, Subhajit Bhar +2
We report non-invasive detection of spin coherence in a collection of Raman-driven cold atoms using dispersive Faraday rotation fluctuation measurements, which opens up new possibi…
A real time digital receiver for correlation measurements in atomic systems
V. Mugundhan, Maheswar Swar, Subhajit Bhar +1
We present the development and characterization of a generic, reconfigurable, low-cost ( 350 USD) software-defined digital receiver system (DRS) for temporal correlation measure…
Measurements and analysis of response function of cold atoms in optical molasses
Subhajit Bhar, Maheswar Swar, Urbashi Satpathi +4
We report our experimental measurements and theoretical analysis of the position response function of a cloud of cold atoms residing in the viscous medium of an optical molasses an…
Measurements of spin properties of atomic systems in and out of equilibrium via noise spectroscopy
Maheswar Swar, Dibyendu Roy, Dhanalakshmi D +3
We explore the applications of spin noise spectroscopy (SNS) for detection of the spin properties of atomic ensembles in and out of equilibrium. In SNS, a linearly polarized far-de…
