  • A simple atomic beam oven with a metal thermal break 
    VISHWAKARMA, CHETAN; MANGAONKAR, JAY; PATEL, KUSHAL; VERMA, GUNJAN; SARKAR, SUMIT; RAPOL, UMAKANT D. (AIP Publishing, 2019-05)
    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 problem of thermal isolation of the oven region ...
  • Interplay between quantum diffusion and localization in the atom-optics kicked rotor 
    MAURYA, S. SAGAR; PATEL, KUSHAL; DUTTA, PRANAB; BISWAS, KORAK; MANGAONKAR, JAY; SANTHANAM, M. S.; RAPOL, UMAKANT D. (American Physical Society, 2022-09)
    Atom-optics kicked rotor represents an experimentally reliable version of the paradigmatic quantum kicked rotor system. In this system, a periodic sequence of kicks are imparted to the cold atomic cloud. After a short ...
  • A Decade of Advancement of Quantum Sensing and Metrology in India Using Cold Atoms and Ions 
    DUTTA, PRANAB; MAURYA, S. SAGAR; PATEL, KUSHAL; BISWAS, KORAK; Mangaonkar, Jay; Sarkar, Sumit; RAPOL, UMAKANT D. (Springer Nature, 2022-10)
    Ultracold atoms and ions provide novel test-beds for quantum sensing and metrology. Technological advancement towards the construction of ultrastable and narrow linewidth lasers, optical frequency combs, and microwave ...
  • Machine-learning-based automated loading of strontium isotopes into magneto-optical trap 
    BISWAS, KORAK; PATEL, KUSHAL; MAURYA, S. SAGAR; DUTTA, PRANAB; RAPOL, UMAKANT D. (AIP Publishing, 2023-07)
    We implemented optimization techniques of machine learning (ML) to obtain the mutually exclusive sets of experimental parameters that maximize the number of strontium atoms of different isotopes (88Sr, 86Sr, and 87Sr) in ...
  • Comparative analysis of phase noise for different configurations of Bragg lattice for an atomic gravimeter with Bose-Einstein condensate 
    DUTTA, PRANAB; MAURYA, S. SAGAR; BISWAS, KORAK; PATEL, KUSHAL; RAPOL, UMAKANT D. (AIP Publishing, 2024-01)
    We perform a comparative study of the phase noise induced in the lasers used for Bragg diffraction in a Bose-Einstein condensate-based quantum gravimeter where the Bragg beams are generated using two different configurations. ...
  • Spectroscopy of the 5s5p 3P0 → 5s5d 3D1 transition of strontium using laser cooled atoms 
    PATEL, KUSHAL; Gakkhar, Palki; BISWAS, KORAK; MAURYA, S. SAGAR; DUTTA, PRANAB; LAL, VISHAL; Mani, B. K.; RAPOL, UMAKANT D. (IOP Publishing Ltd, 2024-05)
    This article presents spectroscopy results of the 5s5p P-3(0) -> 5s5d D-3(1) transition in all isotopes of laser cooled Sr atoms and the utility of this transition for repumping application. By employing the 5s5p P-3(0) ...
