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 are new states of quantum matter which cannot be adiabatically
connected to conventional insulators and semiconductors. They are characterized by a full …

Topological phases of matter have captured our imagination over the past few years, with
tantalizing properties such as robust edge modes and exotic non-Abelian excitations, and …

The prediction and experimental verification of the quantum spin Hall state marked the
discovery of a new state of matter now known as topological insulators. Two-dimensional …

Dirac fermions have been studied intensively in condensed matter physics in recent years.
Many theoretical predictions critically depend on the number of valleys where the Dirac …

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 …

Time-reversal-invariant topological superconductors have a full paring gap in the bulk and
gapless Majorana states at the edge or on the surface. Here, we theoretically propose …

We evaluate the low-temperature conductance of a weakly interacting one-dimensional
helical liquid without axial spin symmetry. The lack of that symmetry allows for inelastic …

Most quantum states of condensed matter are classified by the symmetries they break. For
example, crystalline solids break translational symmetry, and ferromagnets break rotational …

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 …
