I am currently working on the dynamics of open quantum many-body systems coupled strongly with the environment, i.e., non-Markovian dynamics using the TEMPO framework for my master thesis. Previously, I have worked on quantum many-body systems on topics like many-body localization(MBL), ergodicity, thermalization, and quantum transport, to name a few. I am well-skilled with tensor network algorithms like the DMRG, TEBD, TEMPO, and IBM's qiskit library. My work, "Geometric quenches in quasi-disordered lattice system," with Dr. Ranjan Modak, has been published in Physical Review B. Apart from that, I have worked on Quantum Simulations and Quantum Machine Learning as part of IBM's qiskit Summer School, hackathons, and IBM challenges and implemented them using IBM qiskit's library.

July 2018 - May 2023 (Expected)
Supervisor : Dr. Rajeev Singh• Aug 2021 - Ongoing
Working on Open-Quantum Systems, which are strongly coupled with the environment and their dynamics.
Supervisor : Dr. Rajeev Singh• June 2020 - July 2021
Studied quantum quench in a Heisenberg spin-chain and carried out the computations using state-of-the-art tensor network techniques like the Density Matrix Renormalization Group (DMRG)and Time-Evolving Block Decimation (TEBD).
Supervisor : Dr. Rajeev Singh• Jan 2020 - May 2020
Studied photon transport through an atomic medium modeled by a one-dimensional interacting spin chain coupled to photon baths at the boundaries.
Supervisor : Professor Subhro Bhattacharjee• May 2022 - Ongoing
Currently analysing the simulation results after studying a spin 1/2 sawtooth chain with competing Heisenberg antiferromagnetic interactions between their nearest neighbors. Utilized the DMRG technique to characterize the ground-state phase diagram in the spin 1/2 sawtooth chain.
Supervisor : Dr. Ranjan Modak• May 2021 - Jan 2022
Studied a geometric quench on a system of fermions in the one-dimensional lattice in the presence of a quasiperiodic potential using the DMRG and TEBD techniques. Used features like the site occupation and the spreading of the entanglement with time to characterize the localization-delocalization transition.
