We review theoretical and experimental highlights in transport in two-dimensional
topological materials over the last five years. Topological materials comprise topological …

A variety of monolayer crystals have been proposed to be two-dimensional topological
insulators exhibiting the quantum spin Hall effect (QSHE), possibly even at high …

A two-dimensional topological insulator (2DTI) is guaranteed to have a helical one-
dimensional edge mode,,,,,,,,,, in which spin is locked to momentum, producing the quantum …

Atomically thin topological materials are attracting growing attention for their potential to
radically transform classical and quantum electronic device concepts. Among them is the …

The existence of inequivalent valleys K and K′ in the momentum space of 2D hexagonal
lattices provides a new electronic degree of freedom, the manipulation of which can …

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

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 …

Evidence for the quantum spin Hall effect (QSHE) has been reported in several experimental
systems, in the form of edge conductance approaching a quantized value at zero magnetic …

We study low-temperature phases and edge-state conductance of an interacting composite
(1+ 1/n) Abelian helical edge state made of a regular helical liquid carrying charge e and a …

Quantum spin Hall edge channels hold great promise as dissipationless one-dimensional
conductors. However, the ideal quantized conductance of 2 e 2/h is only found in very short …
