Canceling the cavity length induced phase noise in an optical ring cavity for phase shift measurement and spin squeezing

Enlong Wang, Gunjan Verma, Jonathan N. Tinsley +2

We demonstrate a new method of light phase shift measurement using a high-finesse optical ring cavity which exhibits reduced phase noise due to cavity length fluctuations. Two lase…

A simple atomic beam oven with a metal thermal break

Chetan Vishwakarma, Jay Mangaonkar, Kushal Patel +3

We report the design and construction of a simple, easy to machine high-temperature oven for generating an atomic beam in laser cooling experiments. This design eliminates the prob…

Dark solitons generation and their instability dynamics in two dimensional condensates

Gunjan Verma, Umakant D. Rapol, Rejish Nath

We analyze numerically the formation and the subsequent dynamics of two-dimensional matter wave dark solitons in a Thomas-Fermi rubidium condensate using various techniques. An ini…

Non-exponential decoherence and subdiffusion in atom-optics kicked rotor

Sumit Sarkar, Sanku Paul, Chetan Vishwakarma +5

Quantum systems lose coherence upon interaction with the environment and tend towards classical states. Quantum coherence is known to exponentially decay in time so that macroscopi…

Bose-Einstein Condensation in an electro-pneumatically transformed quadrupole-Ioffe magnetic trap

Sunil Kumar, Sumit Sarkar, Gunjan Verma +3

We report a novel approach for preparing a Bose-Einstein condensate (BEC) of Rb atoms using electro-pneumatically driven transfer of atoms into a Quadrupole-Ioffe magnetic t…
