The Group


*Tanmoy Das, Group leader.
*Ananya Ghatak, National Postdoc Fellow.
- She has done her PhD from BHU in 2016. She is working on non-Hermitian quantum phases of matters. She has recently published a pioneering work on the theory of non-Hermitian superconductivity. Now she is working on non-Hermitian topological insulators.
*Gaurav Kumar Gupta, PhD student.
- Gaurav works modelings of interaction induced topological phases. He has proposed the idea of quantum spin Hall density wave insulator. Now he is is working on axin-Higgs modes interaction and how that impact quantum phase transitions. He is also fluent in doing density function theory (DFT) calculation using VASP.
*Sujay Ray, PhD student.
- Sujay works on strongly correlated materials. He has specialized on the calculation of momentum-dependent self-energy using momentum-resolved density fluctuation (MRDF) method. He is now focusing on investigating the anomalous transport and thermodynamical properties resulting from strong momentum dependent self-energy. Sujay also performs DFT) calculation using VASP
*Priyo Adhikary, PhD student.
- Priyo is working on developing theory of superconductivity from valence fluctuations.
*Partha Sarathi Rana, PhD student.
- Partha is working on developing theormodynamical and statistical description of non-Hermitian quantum phases.
*Kale Balayogendra, PhD student.
- Balayogengra is working developing machine learning techniques to solve many-body problems in condensed matter systems.
*Surabhi Saha, PhD student.
- Surabhi is working on developing Landau level theory in time-dependent systems.
