This article reviews recent developments in the non-Hermitian skin effect (NHSE),
particularly on its rich interplay with topology. The review starts off with a pedagogical …

Electronic states in quantum materials can be engineered by light irradiation, which is
greatly advanced by ab-initio computational predictions in realistic light-matter coupled …

As a novel type of fermionic state, the hybrid nodal loop with the coexistence of both type-I
and type-II band crossings has attracted intense research interest. However, it remains a …

In this work, we theoretically investigate the light-induced topological phases and finite-size
crossovers in a paradigmatic quantum spin Hall (QSH) system with high-frequency pumping …

Floquet engineering, the concept of tailoring a system by a periodic drive, is increasingly
exploited to design and manipulate topological phases of matter. In this work we study …

The valley-polarized quantum anomalous Hall (VQAH) state, which forwards a strategy for
combining valleytronics and spintronics with nontrivial topology, attracts intensive interest in …

Creating and manipulating topological states is a key goal of condensed matter physics.
Periodic driving offers a powerful method to manipulate electronic states, and even to create …

The chain-type nodal loops in the reciprocal space can generate exotic nodal chain
fermions. Here, we report that Li2XY (X= Ca, Ba; Y= Si, Ge) compounds are ideal inner …

Motivated by the recent experimental realization of the half-quantized Hall effect phase in a
three-dimensional (3D) semimagnetic topological insulator [M. Mogi, Nat. Phys. 18, 390 …

This work reports the general design and characterization of two exotic, anomalous
nonequilibrium gapless topological phases. In equilibrium systems, the Weyl nodes or the …
