Doppler-Enhanced Quantum Magnetometry with thermal Rydberg atoms
Shovan Kanti Barik, Silpa B S, M Venkat Ramana +2
We report experimental measurements showing how one can combine quantum interference and thermal Doppler shifts at room temperature to detect weak magnetic fields. We pump ${}^{87}…
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…
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…
Universality of the three-body Efimov parameter at narrow Feshbach resonances
Sanjukta Roy, Manuele Landini, Andreas Trenkwalder +6
We measure the critical scattering length for the appearance of the first three-body bound state, or Efimov three-body parameter, at seven different Feshbach resonances in ultracol…
Direct evaporative cooling of 39K atoms to Bose-Einstein condensation
Manuele Landini, Sanjukta Roy, Giacomo Roati +4
We report the realization of Bose-Einstein condensates of 39K atoms without the aid of an additional atomic coolant. Our route to Bose-Einstein condensation comprises Sub Doppler l…
