Hello, my name is Bhaskar Barman.
đ
Iâm currently a fifth-year Physics major enrolled in the BS-MS Dual Degree program at the Indian Institute of Science Education and Research (IISER) Kolkata. My academic interests lie broadly in the field of open quantum systems, quantum information theory and Quantum Thermodynamics, with a deep fascination towards how modern Quantum technologies are shaping in.
Over the past few years, Iâve engaged in multiple research projects that allowed me to explore dynamics of Quantum systems using Lindblad master equation, then entanglement dynamics in spin chain, and fluctuation-regulated quantum master equations. These experiences have not only sharpened my mathematical and computational skills but also sparked a long-term interest in quantum thermodynamics and quantum foundations.
Outside of coursework and research, I actively participate in seminars, workshops, and outreach programs related to physics and quantum computing. I have also given talks to promote STEM education and have been involved in organizing events like IBMâs Qiskit Fall Fest to foster a community of learners around quantum technologies.
Beyond academics, I find joy in traveling, trekking, and exploring natureâoften capturing moments through photography. These adventures help me stay grounded and bring a sense of balance to my academic life.
I aspire to pursue a research career that allows me to contribute to the understanding of complex quantum systems and devices and its applications to near-term quantum technologies. Overall, I am a dedicated and passionate individual with a strong commitment to advancing my knowledge and making meaningful contributions to the field of Quantum thermodynamics and open Quantum systems .

⢠I am looking into how information can act as a resource for enhancing work extraction from charged Quantum
batteries even after considering the cost.
⢠We consider a Q.H.O as a Quantum battery and a T.L.S as a meter. This project entails some simple but beautiful
relations of temperature and suitable work extraction regime, time evolution dynamics of the protocol.
IISER Kolkata (Under Prof. Rangeet Bhattacharyya)
⢠Studied the dynamics of two interacting spin-½ systems using the Fluctuation-Regulated Quantum Master Equation (FRQME).
⢠Derived dynamical observables under dipolar interaction, capturing both unitary and dissipative effects from first and second-order terms of FRQME.
⢠Numerical simulations revealed the dissipative nature of the system dynamics and the impact of information loss during interactions.

IISER Kolkata (Under Prof. Rangeet Bhattacharyya)
⢠Investigated entanglement dynamics in a three-qubit spin chain using QuTiP simulations.
⢠Analyzed entanglement transfer starting from a Bell state, evolved under Heisenberg-XY and XXZ Hamiltonians.
⢠Quantified entanglement using concurrence and studied redistribution through unitary evolution and partial tracing.
⢠Explored the effects of coupling strength, dephasing, and dissipation, highlighting key factors influencing quantum communication and teleportation.

IIT Jodhpur
⢠I did a summer internship under Prof. Subhashis Banarjee on Open quantum systems where I first learnt about Lindblad master equations. Derived explicitly the decay of two-level system and computationally see the Bloch vector evolution of states using âMesolverâ of âQutipâ module. Then verified the Markovian and non-Markovian nature of the Lindblad master equation. Currently working on Ergotropy.
PRL, Ahmedabad
⢠I did a summer internship under Prof. Navinder Singh on Hot electron in Metal where we derived net phonon generation rate in metals and then using that relation derived energy transfer rate from electron to phonon in low and high temperature limit.

⢠I did a Term paper project in 6th semester as a part of Advanced Quantum Mechanics course under the supervision of Prof. Sourin Das on Berry phase, diabolical and Chern number calculation. We calculated ¹1, ¹2 Chern number and lastly tried to explain the unique pattern of Chern numbers in Fe8 molecule.
