Interplay of chiral and helical states in a Quantum Spin Hall Insulator lateral junction

M. R. Calvo, F. de Juan, R. Ilan +11

We study the electronic transport across an electrostatically-gated lateral junction in a HgTe quantum well, a canonical 2D topological insulator, with and without applied magnetic…

Observation of the universal magnetoelectric effect in a 3D topological insulator

V. Dziom, A. Shuvaev, A. Pimenov +9

The electrodynamics of topological insulators (TIs) is described by modified Maxwell's equations, which contain additional terms that couple an electric field to a magnetization an…

Josephson radiation from gapless Andreev bound states in HgTe-based topological junctions

Russell S. Deacon, Jonas Wiedenmann, Erwann Bocquillon +9

Frequency analysis of the rf emission of oscillating Josephson supercurrent is a powerful passive way of probing properties of topological Josephson junctions. In particular, measu…

Gapless Andreev bound states in the quantum spin Hall insulator HgTe

Erwann Bocquillon, Russell S. Deacon, Jonas Wiedenmann +6

In recent years, Majorana physics has attracted considerable attention in both theoretical and experimental studies due to exotic new phenomena and its prospects for fault-tolerant…

Controlled Finite Momentum Pairing and Spatially Varying Order Parameter in Proximitized HgTe Quantum Wells

Sean Hart, Hechen Ren, Michael Kosowsky +7

Conventional -wave superconductivity is understood to arise from singlet pairing of electrons with opposite Fermi momenta, forming Cooper pairs whose net momentum is zero [1]. S…
