Topological zero-reflection points in multi-terminal quantum wire junctions
Abhiram Soori, Udit Khanna, Diptiman Sen
The paper analyzes scattering in non‑interacting multi‑terminal quantum wire junctions and shows that dihedral‑symmetric junctions can exhibit exact zero‑reflection points, which a…
Even-denominator fractional quantum Hall states in the zeroth Landau level of ABA trilayer graphene
Tanima Chanda, Simrandeep Kaur, Harsimran Singh +6
The paper reports the observation of robust even‑denominator fractional quantum Hall states in the zeroth Landau level of ABA trilayer graphene, linking their stability to inversio…
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…
Anomalous Transport Gaps of Fractional Quantum Hall Phases in Graphene Landau Levels are Induced by Spin-Valley Entangled Ground States
Jincheng An, Ajit C. Balram, Udit Khanna +1
We evaluate the transport gaps in the most prominent fractional quantum Hall states in the and Landau Levels of graphene, accounting for the Coulo…
Energy Gap Modulation in Proximitized Superconducting Puddles of Graphene
Yuxiao Wu, Udit Khanna, Eyal Walach +2
We investigated proximity-induced superconductivity in a graphene-insulating InO bilayer system through gate-controlled transport measurements. Distinct oscillations in the differe…
Decoherence in electron transport: back-scattering, effect on interference and rectification
Abhiram Soori, Udit Khanna
Decoherence is an undesirable, but ubiquitous phenomenon in quantum systems. Here, we study the effect of partial decoherence, induced via a Büttiker probe, on two-terminal electr…
