We develop a method to predict the existence of edge states in graphene ribbons for a large
class of boundaries. This approach is based on the bulk-edge correspondence between the …

We study the extended Su-Schrieffer-Heeger model with both nearest-neighbor and next-
nearest-neighbor hopping strengths cyclically modulated and find the family of the model …

The organization of the electrons in the ground state is classified by means of topological
invariants, defined as global properties of the wave function. Here we address the Chern …

We explore the nonequilibrium response of Chern insulators. Focusing on the Haldane
model, we study the dynamics induced by quantum quenches between topological and …

We show the controllable excitation transmission can be implemented based on the
topologically protected edge channel in the modulated Su-Schrieffer-Heeger model with …

We show how to implement the unidirectional topological excitation transmission in the Rice-
Mele model. We find that the unidirectional excitation transmissions can be implemented via …

Zigzag nanoribbons hosting the Haldane Chern insulator model are considered. In this
context, a reentrant topological phase, characterized by the emergence of quasi zero …

Topological pumping has numerous applications in quantum information processing, eg, the
spatial entanglement distribution of the two correlated particles via the disordered bulk …

The modern expressions for polarization P and orbital magnetization M are k-space
integrals. But a genuine bulk property should also be expressible in r space, as an …

We study the topological properties of the two-body bound states in an interacting Haldane
model as a function of interparticle interactions. In particular, we identify topological phases …
