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 …

We have engineered electron-hole bilayers of inverted InAs/GaSb quantum wells, using
dilute silicon impurity do** to suppress residual bulk conductance. We have observed …

One-dimensional helical liquids can appear at boundaries of certain condensed matter
systems. Two prime examples are the edge of a quantum spin Hall insulator and the hinge …

Van der Waals (vdW) heterostructures formed by two-dimensional atomic crystals provide a
powerful approach towards designer condensed matter systems,,,,,,,,,,,,,,. Incommensurate …

A two-dimensional (2D) topological insulator exhibits the quantum spin Hall (QSH) effect, in
which topologically protected conducting channels exist at the sample edges. Experimental …

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 …

We present transport and scanning SQUID measurements on InAs/GaSb double quantum
wells, a system predicted to be a two-dimensional topological insulator. Top and back gates …

A primary goal of the upcoming Deep Underground Neutrino Experiment (DUNE) is to
measure the O (10) MeV neutrinos produced by a Galactic core-collapse supernova if one …

Among the theoretically predicted two-dimensional topological insulators, InAs/GaSb double
quantum wells (DQWs) have a unique double-layered structure with electron and hole …

The electrons in the edge channels of two-dimensional topological insulators can be
described as a helical Tomonaga-Luttinger liquid. They couple to nuclear spins embedded …
