Biased Consensus Dynamics on Regular Expander Graphs
Oindrila Deb, Arpan Mukhopadhyay
Consensus protocols play an important role in the study of distributed algorithms. In this paper, we study the effect of bias on two popular consensus protocols, namely, the {\em v…
Electronic confinement of surface states in a topological insulator nanowire
Ruchi Saxena, Eytan Grosfeld, Sebastian E de Graaf +4
We analyze the confinement of electronic surface states in a model of a topological insulator nanowire. Spin-momentum locking in the surface states reduces unwanted backscattering…
Tuning interactions between spins in a superconductor
Hao Ding, Yuwen Hu, Mallika T. Randeria +5
Novel many-body and topological electronic phases can be created in assemblies of interacting spins coupled to a superconductor, such as one-dimensional topological superconductors…
Yu-Shiba-Rusinov States and Ordering of Magnetic Impurities Near the Boundary of a Superconducting Nanowire
Oindrila Deb, Silas Hoffman, Daniel Loss +1
We theoretically study the spectrum induced by one and two magnetic impurities near the boundary of a one-dimensional nanowire in proximity to a conventional -wave superconducto…
Josephson junctions of multiple superconducting wires
Oindrila Deb, K. Sengupta, Diptiman Sen
We study the spectrum of Andreev bound states and Josephson currents across a junction of superconducting wires which may have - or -wave pairing symmetries and develop a…
Generating surface states in a Weyl semi-metal by applying electromagnetic radiation
Oindrila Deb, Diptiman Sen
We show that the application of circularly polarized electromagnetic radiation on the surface of a Weyl semi-metal can generate states at that surface. These states can be characte…
Granular topological insulators
Abhishek Banerjee, Oindrila Deb, Kunjalata Majhi +3
Granular conductors form an artificially engineered class of solid state materials wherein the microstructure can be tuned to mimic a wide range of otherwise inaccessible physical…
Transport across a system with three p-wave superconducting wires: effects of Majorana modes and interactions
Oindrila Deb, Manisha Thakurathi, Diptiman Sen
We study the effects of Majorana modes and interactions between electrons on transport in a one-dimensional system with a junction of three p-wave superconductors (SCs) which are c…
Majorana modes and transport across junctions of superconductors and normal metals
Manisha Thakurathi, Oindrila Deb, Diptiman Sen
We study Majorana modes and transport in one-dimensional systems with a -wave superconductor (SC) and normal metal leads. For a system with a SC lying between two leads, it is k…
Edge states of a three-dimensional topological insulator
Oindrila Deb, Abhiram Soori, Diptiman Sen
We use the bulk Hamiltonian for a three-dimensional topological insulator such as to study the states which appear on its various surfaces and along the edge betwee…
Transport across a junction of topological insulators and a superconductor
Abhiram Soori, Oindrila Deb, K. Sengupta +1
We study transport across a line junction lying between two orthogonal topological insulator surfaces and a superconductor which can have either s-wave (spin-singlet) or p-wave (sp…
Junction between surfaces of two topological insulators
Diptiman Sen, Oindrila Deb
We study the properties of a line junction which separates the surfaces of two three-dimensional topological insulators. The velocities of the Dirac electrons on the two surfaces m…
