Anomalous topology and synthetic flat band in multi-terminal Josephson Junctions
Aabir Mukhopadhyay, Udit Khanna, Sourin Das
Andreev bound states trapped in a multi-terminal Josephson junction (JJ) can be assigned a synthetic band topology owing to their periodic dependence on the Josephson phase bias. W…
Phase diagram of the quantum Hall state in bilayer graphene
Udit Khanna, Ke Huang, Ganpathy Murthy +5
Bilayer graphene exhibits a rich phase diagram in the quantum Hall regime, arising from a multitude of internal degrees of freedom, including spin, valley, and orbital indices. The…
Quantum spin Hall insulator in proximity with a superconductor: Transition to the Fulde-Ferrell-Larkin-Ovchinnikov state driven by a Zeeman field
Suman Jyoti De, Udit Khanna, Sumathi Rao +1
We investigate the effects of introducing a boost (a Zeeman field parallel to the spin quantization axis) at the proximitized helical edge of a two-dimensional (2D) quantum spin Ha…
