Ipsita Das

Ipsita Das is a PCCM Postdoctoral Fellow at Princeton University, focusing on quantum materials and graphene-based systems. Her research explores correlated electron phenomena, twisted bilayer graphene, and advanced materials processing. Key areas of investigation include electron-electron interactions in graphene, superconductivity, and quantum phase transitions under magnetic fields.

Her work combines experimental techniques such as quantum twisting microscopy, high-energy ball milling, and advanced electrical characterization. Notable contributions involve fabricating high-quality twisted bilayer graphene devices and studying their electronic properties under extreme conditions. She also investigates novel composite materials, including medium-entropy alloys reinforced aluminum composites.

Recent studies highlight reentrant correlated insulators, symmetry-broken Chern insulators, and quantum noise-limited amplification using graphene Josephson junctions. These findings bridge fundamental physics with potential applications in quantum electronics and low-loss microwave systems.

Ipsita’s research also extends to strange metal behavior and the interplay of superconducting and insulating orders in magic-angle graphene bilayers. Her work is supported by experimental data from cutting-edge facilities, emphasizing reproducible fabrication and precise characterization.
