Sagar Sarkar

Sagar Sarkar is a Postdoctoral Research Fellow in the Department of Physics and Astronomy at Uppsala University, affiliated with both the Materials Theory and Quantum Matter Theory research groups. His work focuses on theoretical investigations of quantum materials and condensed matter systems.

His research centers on magnetic phenomena in topological insulators, particularly transition metal-doped bismuth selenide (Bi2Se3). Using computational methods and first-principles calculations, he explores electronic structure, spin interactions, and quantum properties relevant to next-generation spintronic and quantum computing applications. His approach bridges fundamental physics with materials engineering for novel device concepts.

His recent 2024 publication in Physical Review B exemplifies his focus on quantum matter, demonstrating how magnetic coupling mechanisms in doped topological insulators can be systematically analyzed through theoretical modeling.

He operates within Uppsala University's Ångström Laboratory research ecosystem, contributing to Sweden's advanced materials science infrastructure through collaborative theoretical work.
