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 …
According to quantum mechanics, a harmonic oscillator can never be completely at rest. Even in the ground state, its position will always have fluctuations, called the zero-point …

We have engineered electron-hole bilayers of inverted InAs/GaSb quantum wells, using dilute silicon impurity doping to suppress residual bulk conductance. We have observed …
The hallmark of a topologically insulating state of matter in two dimensions protected by time- reversal symmetry is the existence of chiral edge modes propagating along the perimeter of …
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 …
Topological superconductivity is an exotic state of matter that supports Majorana zero- modes, which have been predicted to occur in the surface states of three-dimensional …

Electronic correlations give rise to fascinating macroscopic phenomena such as superconductivity, magnetism, and topological phases of matter. Although these …
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 …
