Non-resonant inter-species interaction and its effect on the position response function of cold atoms
Anirban Misra, Urbashi Satpathi, Supurna Sinha +2
In the context of non-equilibrium statistical physics, the position response of a particle, coupled to a bath, subjected to an external force is a topic of broad interest. A topic…
Effect of light-assisted tunable interaction on the position response function of cold atoms
Anirban Misra, Urbashi Satpathi, Supurna Sinha +2
The position response of a particle subjected to a perturbation is of general interest in physics. We study the modification of the position response function of an ensemble of col…
Fast loading of a cold mixture of Sodium and Potassium atoms from compact and versatile cold atomic beam sources
Sagar Sutradhar, Anirban Misra, Gourab Pal +3
We present the design, implementation and detailed experimental characterization of two-dimensional Magneto-optical traps (MOT) of bosonic Na and K atoms for loading…
Transition frequency measurement of highly excited Rydberg states of 87Rb for a wide range of principal quantum numbers
Silpa B S, Shovan Kanti Barik, Saptarishi Chaudhuri +1
We report our measurements of the absolute transition frequencies of 5P_3/2,F = 3 to nS and nD Rydberg states of 87Rb with high principal quantum numbers in a wide range of values…
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…
Two-electron quantum dot in a magnetic field: Analytic solution for finite potential model
S. Chaudhuri
The energy levels of two interacting electrons in a 2D quantum dot confined by a finite Gaussian potential and subjected to a uniform magnetic field perpendicular to the plane of t…
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…
Transport of a Bose gas in 1D disordered lattices at the fluid-insulator transition
Luca Tanzi, Eleonora Lucioni, Saptarishi Chaudhuri +5
We investigate the momentum-dependent transport of 1D quasi-condensates in quasiperiodic optical lattices. We observe a sharp crossover from a weakly dissipative regime to a strong…
