Atom interferometry using temporal Talbot effect on a Bose-Einstein condensate
Jay Mangaonkar, Chetan Vishwakarma, S. Sagar Maurya +4
We experimentally investigate a uniform pulse sequence in which atom interference is realized using the temporal matter-wave Talbot effect in an atom-optic kicked rotor system. Mul…
Non-monotonic diffusion rates in atom-optics Lévy kicked rotor
Sanku Paul, Sumit Sarkar, Chetan Vishwakarma +3
The dynamics of chaotic Hamiltonian systems such as the kicked rotor continues to guide our understanding of transport and localization processes. The localized states of the quant…
Study of loss dynamics of strontium in a magneto-optical trap
Chetan Vishwakarma, Kushal Patel, Jay Mangaonkar +3
Collisions with background atoms are known to induce a significant shift in the frequency of state-of-the-art optical atomic clocks and contribute to state decoherence in cold atom…
Design, Fabrication and Characterization of nanoplasmonic lattice for trapping of ultracold atoms
Sunil Kumar, Manav Shah, Ajith P. Ravishankar +5
Ultracold atom-traps on a chip enhances the practical application of atom traps in quantum information processing, sensing, and metrology. Plasmon mediated near-field optical poten…
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…
Diffraction of a CW atom laser in the Raman-Nath regime
Sumit Sarkar, Jay Mangaonkar, Chetan Vishwakarma +1
Atom interferometry is the most successful technique for precision metrology. However, current interferometers using ultracold atoms allows one to probe the interference pattern on…
