Complementary screening for quantum spin Hall insulators in two-dimensional exfoliable materials

Nicola Marzari, Davide Campi, Antimo Marrazzo, Davide Grassano

Quantum spin Hall insulators are a class of topological materials that has been extensively studied during the past decade. One of their distinctive features is the presence of a finite band gap in the bulk and gapless, topologically protected edge states ...

Superior robustness of anomalous non-reciprocal topological edge states

Romain Christophe Rémy Fleury, Zhechen Zhang, Pierre Delplace

Robustness against disorder and defects is a pivotal advantage of topological systems, manifested by the absence of electronic backscattering in the quantum-Hall and spin-Hall effects, and by unidirectional waveguiding in their classical analogues. Two-dim ...

Guided accumulation of active particles by topological design of a second-order skin effect

Ignacio Pagonabarraga Mora, Samuel Sanchez

Collective guidance of out-of-equilibrium systems without using external fields is a challenge of paramount importance in active matter, ranging from bacterial colonies to swarms of self-propelled particles. Designing strategies to guide active matter and ...

Tilted double Dirac cone and anisotropic quantum-spin-Hall topological insulator in mechanical granular graphene

Romain Christophe Rémy Fleury, Georgios Theocharis

Dirac degeneracies are essential ingredients to control topological charge exchanges between bands and trigger the unique edge transport properties of topological materials. In addition, when Dirac cones are tilted, exotic phenomena can emerge such as anom ...

Controlling the Quantum Spin Hall Edge States in Two-Dimensional Transition Metal Dichalcogenides

Oleg Yazyev, Artem Pulkin

Two-dimensional transition metal dichalcogenides (TMDs) of Mo and W in their 1T' crystalline phase host the quantum spin Hall (QSH) insulator phase. We address the electronic properties of the QSH edge states by means of first-principles calculations perfo ...

Topological wave insulators: a review

Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad

Originally discovered in condensed matter systems, topological insulators (TIs) have been ubiquitously extended to various fields of classical wave physics including photonics, phononics, acoustics, mechanics, and microwaves. In the bulk, like any other in ...
