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…
Induced Superconductivity in the Quantum Spin Hall Edge
Sean Hart, Hechen Ren, Timo Wagner +6
Topological insulators are a newly discovered phase of matter characterized by a gapped bulk surrounded by novel conducting boundary states. Since their theoretical discovery, thes…
Unexpected edge conduction in HgTe quantum wells under broken time reversal symmetry
Eric Yue Ma, M. Reyes Calvo, Jing Wang +16
The realization of quantum spin Hall (QSH) effect in HgTe quantum wells (QWs) is considered a milestone in the discovery of topological insulators. The QSH edge states are predicte…
Spin polarization of the quantum spin Hall edge states
Christoph Brüne, Andreas Roth, Hartmut Buhmann +5
While the helical character of the edge channels responsible for charge transport in the quantum spin Hall regime of a two-dimensional topological insulator is by now well establis…
Quantum Hall Effect from the Topological Surface States of Strained Bulk HgTe
C. Brüne, C. X. Liu, E. G. Novik +7
We report transport studies on a three dimensional, 70 nm thick HgTe layer, which is strained by epitaxial growth on a CdTe substrate. The strain induces a band gap in the otherwis…
Circular photogalvanic effect in HgTe/CdHgTe quantum well structures
B. Wittmann, S. N. Danilov, V. V. Bel'kov +12
We describe the observation of the circular and linear photogalvanic effects in HgTe/CdHgTe quantum wells. The interband absorption of mid-infrared radiation as well as the intrasu…
Nonlinear magneto-gyrotropic photogalvanic effect
H. Diehl, V. A. Shalygin, L. E. Golub +8
We report on the observation of nonlinear magneto-gyrotropic photogalvanic effect in HgTe/HgCdTe quantum wells. The interband absorption of mid-infrared radiation as well as the in…
