Abstract Materials featuring touching points, localized states, and flat bands are of great interest in condensed matter and artificial systems due to their implications in topology, quantum geometry, superconductivity, and interactions. In this theo

Low-dimensional systems that host Dirac-like physics are of considerable interest, and attention is turning to platforms with increasingly complex symmetries as a way of realizing more exotic and novel features. Here, the authors consider Dirac state

We analyze the robustness of corner modes in topological photonic crystals, taking a C_{6}-symmetric breathing honeycomb photonic crystal as an example. First, we employ topological quantum chemistry and Wilson loop calculations to demonstrate that t

In topological systems, a modulation in the gap onset near interfaces can lead to the appearance of massive edge states, as were first described by Volkov and Pankratov. In this work, we study graphene nanoribbons in the presence of intrinsic spin-or

We address the coexistence of massless and massive topological edge states at the interface between two materials with different topological phases. We modify the well-known Bernevig-Hughes-Zhang model to introduce a smooth function describing the ba

In recent years, there have been rapid advances in the parallel fields of electronic and photonic topological crystals. Topological photonic crystals in particular show promise for coherent transport of light and quantum information at macroscopic sc

The fluctuation dissipation theorem is at the heart of equilibrium statistical mechanics. For a system away from thermal equilibrium, generalized nonequilibrium fluctuation relations have been found in recent years. Fluctuation relations reveal the f

Topological states of matter were first discovered in the field of solid-state physics but recent contributions are proving their existence in diverse fields of science. To mention a few, topological surface states have been recently identified in th

We apply two of the most popular tools used in condensed matter physics to the topological characterization of dispersion bands in photonic crystals. We focus on a family of crystals formed by 2D cylinders placed as concentric hexagons in a triangula

Superconducting proximity effects in graphene have received a great deal of attention for over a decade now. This has unveiled a plethora of exotic effects linked to the specificities of graphene's electronic properties. The vast majority of the rela
