Enhancement of Superconductivity upon reduction of carrier density in proximitized graphene
Gopi Nath Daptary, Udit Khanna, Eyal Walach +3
The superconducting transition temperature (Tc) of a single layer graphene coupled to an Indium oxide (InO) film, a low carrier-density superconductor, is found to increase with de…
Edge Reconstruction and Emergent Neutral Modes in Integer and Fractional Quantum Hall Phases
Udit Khanna, Moshe Goldstein, Yuval Gefen
This paper comprises a review of our recent works on fractional chiral modes that emerge due to edge reconstruction in integer and fractional quantum Hall (QH) phases. The new part…
Fractional Edge Reconstruction in Integer Quantum Hall Phases
Udit Khanna, Moshe Goldstein, Yuval Gefen
Protected edge modes are the cornerstone of topological states of matter. The simplest example is provided by the integer quantum Hall state at Landau level filling unity, which sh…
Magnetic Flux Periodicity in Second Order Topological Superconductors
Suman Jyoti De, Udit Khanna, Sumathi Rao
The magnetic flux periodicity of is a well known manifestation of Cooper pairing in typical s-wave superconductors. In this paper we theoretically show that the flu…
Symmetry and correlation effects on band structure explain the anomalous transport properties of (111) LaAlO/SrTiO
Udit Khanna, Prasanna K. Rout, Michael Mograbi +5
The interface between the two insulating oxides SrTiO and LaAlO gives rise to a two-dimensional electron system with intriguing transport phenomena, including superconducti…
Spin Mode-Switching at the Edge of a Quantum Hall System
Udit Khanna, Ganpathy Murthy, Sumathi Rao +1
Quantum Hall states can be characterized by their chiral edge modes. Upon softening the edge potential, the edge has long been known to undergo spontaneous reconstruction driven by…
