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 …

The discovery of graphene has led to the devotion of intensive efforts, theoretical and
experimental, to produce two-dimensional (2D) materials that can be used for developing …

Combining physics, mathematics and computer science, topological quantum computation
is a rapidly expanding research area focused on the exploration of quantum evolutions that …

We analyze translationally invariant insulators with inversion symmetry that fall outside the
current established classification of topological insulators. These insulators exhibit no edge …

The ground state of translationally invariant insulators comprises bands which can assume
topologically distinct structures. There are few known examples where this distinction is …

We study three-dimensional insulators with inversion symmetry in which other point group
symmetries, such as time reversal, are generically absent. We find that certain information …

We investigate the properties of the Lieb lattice, that is, a face-centered square lattice,
subjected to external gauge fields. We show that an Abelian gauge field leads to a peculiar …

We study the spinless and spinful extended Hubbard models with repulsive interactions on
the kagome and the decorated honeycomb (star) lattice. Using Hartree-Fock mean-field …

The structures and properties of van der Waals (vdW) heterojunctions between
semiconducting two-dimensional transition-metal dichalcogenides (2D TMDs) and …

Bound states of two interacting particles moving on a lattice can exhibit remarkable features
that are not captured by the underlying single-particle picture. Inspired by this phenomenon …
