The discovery of the quantum spin Hall effect and topological insulators more than a decade
ago has revolutionized modern condensed matter physics. Today, the field of topological …

Topological insulators have become one of the most active research areas in condensed
matter physics. This article reviews progress on the topic of electronic correlation effects in …

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

Quantum spin Hall devices with edges much longer than several microns do not display
ballistic transport; that is, their measured conductances are much less than e 2/h per edge …

There are only few discoveries and new technologies in physical sciences that have the
potential to dramatically alter and revolutionize our electronic world. Topological insulators …

Topological insulators (TIs) have an insulating bulk but a metallic surface. In the simplest
case, the surface electronic structure of a three-dimensional (3D) TI is described by a single …

We report on the observation of a helical Luttinger liquid in the edge of an InAs/GaSb
quantum spin Hall insulator, which shows characteristic suppression of conductance at low …

We investigate the influence of nuclear spins on the resistance of helical edge states of two-
dimensional topological insulators (2DTIs). Via the hyperfine interaction, nuclear spins allow …

We study the phase diagram of the inverted InAs/GaSb bilayer quantum wells. For a small
tunneling amplitude between the layers, we find that the system is prone to the formation of …

A quantum spin Hall insulator is a two-dimensional state of matter consisting of an insulating
bulk and one-dimensional helical edge states. While these edge states are topologically …
