Anomalous Aharonov-Bohm Interference in the Presence of Edge Reconstruction
Sourav Biswas, Hemanta Kumar Kundu, Rajarshi Bhattacharyya +2
Interferometry is a vital tool for studying fundamental features in the quantum Hall effect (QHE). For instance, Aharonov-Bohm (AB) interference in a quantum Hall interferometer ca…
Electron Pairing of Interfering Interface-Based Edge Modes
Sourav Biswas, Hemanta Kumar Kundu, Vladimir Umansky +1
The remarkable Cooper-like pairing phenomenon in the Aharonov-Bohm interference of a Fabry-Perot interferometer (FPI)operating in the integer quantum Hall regimerem…
Anyonic interference and braiding phase in a Mach-Zehnder Interferometer
Hemanta Kumar Kundu, Sourav Biswas, Nissim Ofek +2
The fractional quantum Hall states have long been predicted to be a testing ground of fractional (anyonic) exchange statistics. These topological states harbor quasiparticles with…
Hidden electronic phase in strained few-layer 1T-TaS2
Sruthi S, Hemanta Kumar Kundu, Prasad Vishnubhotla +1
Layered van der Waals materials are exciting as they often host multiple, competing electronic phases. This article reports experimental observation of the co-existence of insulati…
Transition from three- to two-dimensional Ising superconductivity in few-layer NbSe2 by proximity effect from van der Waals heterostacking
Prakiran Baidya, Divya Sahani, Hemanta Kumar Kundu +7
We report the experimental observation of Ising superconductivity in 3-dimensional NbSe2 stacked with single-layer MoS2. The angular dependence of the upper critical magnetic field…
Does shot noise always provide the quasiparticle charge?
Sourav Biswas, Rajarshi Bhattacharyya, Hemanta Kumar Kundu +5
The fractional charge of quasiparticles is a fundamental feature of quantum Hall effect (QHE) States. The charge has long been measured via shot-noise at moderate temperatures (…
Novel method distinguishing between competing topological orders
Bivas Dutta, Wenmin Yang, Ron Aharon Melcer +6
Quantum Hall states - the progenitors of the growing family of topological insulators -- are rich source of exotic quantum phases. The nature of these states is reflected in the ga…
Effect of dimensionality on the vortex-dynamics in type-II superconductor
Hemanta Kumar Kundu, Kazi Rafsanjani Amin, John Jesudasan +3
We explore the effects of sample dimensionality on vortex pinning in a type-II, low-, s-wave superconductor, NbN, in the presence of a perpendicular magnetic field, . We fi…
Effect of spin-orbit interaction on the vortex dynamics in LaAlO/SrTiO interfaces near the superconducting transition
Gopi Nath Daptary, Hemanta Kumar Kundu, Pramod Kumar +4
Controlling spin-orbit interaction and its effect on superconductivity has been a long-standing problem in two-dimensional inversion symmetry broken superconductors. An open challe…
Quantum phase transition in few-layer NbSe probed through quantized conductance fluctuations
Hemanta Kumar Kundu, Sujay Ray, Kapildeb Dolui +6
We present the first observation of dynamically modulated quantum phase transition (QPT) between two distinct charge density wave (CDW) phases in 2-dimensional 2H-NbSe. There i…
