About Me: This is the Quantum Materials Research Group in the Department of Physics at IIT(ISM) Dhanbad led by myself, Dr. Sudeshna Sen. We explore materials in the quantum domain using theoretical and computational approaches. Quantum Materials are currently the vanguard of modern condensed matter physics. I am interested in the quantum mechanics of strongly correlated electron systems and many-body theory of these systems. I did my Ph.D. from JNCASR, Bangalore, and worked as Post Doctoral Fellow at University College Dublin, Ireland, and TD Lee Institute, Shanghai. I collaborate with several groups from around the globe for my research. To learn more about my education and collaborators navigate to this page .

Research Interest: Theoretical And Computational Condensed Matter 17, Strongly Correlated Electron Systems, Many-electron Theory, Mott And Heavy Fermion Systems, Quantum Impurity Models, Quantum Phase Transition, Nanoelectronics, Topological Systems
