Understanding the dynamics of excitons in two dimensional semiconductors requires a theory that incorporates the essential physics distinct from their three-dimensional counterparts. In addition to the modified dielectric environment, single-particle

As previously explored with sophisticated computational methods, projecting out incomplete components of Bloch wave functions yields `states' that appear to be `spin polarized'. Here, the consequences and physical relevance of this so-called hidden s

Using a tight-binding description, we show how the zero-dimensional state bound to the edge of a single one-dimensional helical chain of tellurium atoms evolves into two-dimensional states on the c-axis surface of the three-dimensional trigonal bulk.

Atomic-scale helices exist as motifs for several material lattices. We examine a tight-binding model for a single one-dimensional monatomic chain with a $p$-orbital basis coiled into a helix. A topologically nontrivial phase emerging from this model

The electronic structure of crystalline materials reflects the influence of underlying discrete symmetries of the atomic lattice. When these symmetries are broken, associated degeneracies in the spectrum of states often split, with important conseque

In many semiconductors, weak spin-orbit coupling to the environment thwarts spin-state decoherence, allowing long bit lifetimes and thus long-distance spin transport in logic devices. However, this long lifetime also sets a stringent---and relatively

Several recent experiments on three-dimensional topological insulators claim to observe a large charge current-induced non-equilibrium ensemble spin polarization of electrons in the helical surface state. We present a comprehensive criticism of such

The electronic structure of (group-III) metal-monochalcogenide monolayers exhibits many unusual features. Some, such as the unusually distorted upper valence band dispersion we describe as a 'caldera', are primarily the result of purely orbital inter
