Displacement field stabilizes even-denominator and partonic fractional quantum Hall states in the Landau levels of Bernal-stacked bilayer graphene
Rakesh K. Dora, Udit Khanna, Ajit C. Balram
Bernal-stacked bilayer graphene (BLG), in which a graphene layer is stacked atop another and laterally shifted by a lattice constant, offers remarkable tunability in its single-par…
Topological zero-reflection points in multi-terminal quantum wire junctions
Abhiram Soori, Udit Khanna, Diptiman Sen
We study scattering in noninteracting multi-terminal quantum wire junctions and show that junctions with dihedral symmetry can exhibit exact zero-reflection points for te…
Synthetic Flat Bands, Hierarchical Topology, and Phase-Fluctuation-Insensitive Quantized Transconductance in Josephson Junctions
Subhadeep Chakraborty, Aabir Mukhopadhyay, Udit Khanna +1
We uncover hierarchy of topological phases within the synthetic Brillouin zone of a three-terminal Josephson junction's (3-TJJ's) Bogoliubov-de Gennes spectrum. We demonstrate that…
