About Me
I am currently a Postdoctoral Researcher in the Department of Physics at Virginia Tech, USA, where I focus on constructing and detecting quantum phases with cold atoms. I earned my PhD from the Indian Institute of Technology Kharagpur, specializing in Quantum Turbulence in Bose-Einstein Condensates. My theoretical research spans various areas within the broad field of Atomic, Molecular, and Optical Physics. With over 6 years of experience, I have developed scientific code in C++ and excel in data post-processing using Python.
I completed my undergraduate studies at the University of North Bengal and my postgraduate studies at the University of Calcutta, where I was awarded the prestigious DST-INSPIRE Scholarship for academic excellence. Recently, I was granted $5000 in Google Cloud Platform (GCP) research credits, which facilitated large-scale simulations of quantum turbulence utilizing advanced GPU architectures for high-performance computing.

Distinguishing superfluid and supersolid phase using vortex motion
We propose an experimental method to distinguish supersolid and superfluid phases using vortex dipole. Vortex dipole behaves separately in these two phases. By tracing the trajectory of the vortices and calculating the correlation between trajectories, one can identify the phase.
Studies on Dipolar Bose-Einstein Condensate
We have done several works on dipolar BEC under different trapping geometries: 2D-3D harmonic potential and 3D bubble trap potential with rotation. We also consider dipolar-dipolar and dipolar-nondipolar multicomponent mixture of 164Dy and 168Er.
2D Quantum Turbulence in Bose-Einstein Condensate
We explore the dynamics of point vortices within a two-component Bose-Einstein Condensate (BEC), examining how interspecies interactions influence quantum turbulence. Our analysis reveals that the scaling laws of turbulence vary depending on the rotation frequency of the obstacle used to generate the vortices.
