Biography:
Dr. Urbashi Satpathi is currently an Assistant Professor (Senior Grade) in Department of Physics and Material Science, JIIT Noida. She did her M.Sc. in Physics from Presidency College, University of Calcutta, and secured first rank in her batch. She got DST-Inspire fellowship for PhD in 2011. In 2016 she finished her PhD from S. N. Bose National Centre for Basic Sciences, Kolkata. Later she did Post-Doctoral research from Raman Research Institute, Bangalore (Feb 2016-Sep-2018) and International Centre for Theoretical Sciences (ICTS-TIFR), Bangalore (Oct 2018-Aug-2021). Then she went to Israel as a Senior Post-Doctoral fellow in Ben-Gurion University of Negev.
She is presently working on open quantum systems mostly in the domain of quantum diffusion and quantum thermodynamics. She is exploring quantum Brownian motion using generalized fluctuation dissipation theorem and linear response theory in different time and temperature regimes. She has also interest in quantum transport for different mesoscopic systems like quantum wire and quantum ring. Her other interests are finding robust soliton solutions for non-integrable systems.
