The classical and quantum Hall effects are important subjects in condensed matter physics.
The emergent 3D quantum Hall effects and nonlinear Hall effect have attracted considerable …

Chiral bulk Landau levels and surface arcs, as the two distinctive features unique to Weyl
semimetals, have each attracted enormous interest. Recent works have revealed that …

To explore the non-Euclidean generalization of higher-order topological phenomena, we
construct a higher-order topological insulator model in hyperbolic lattices by breaking the …

Motivated by the recent experimental realizations of hyperbolic lattices in circuit quantum
electrodynamics and the research interest in the non-Euclidean generalization of topological …

Four-dimensional (4D) topological insulators, which are impossible in real materials, have
attracted much attention by virtue of the recent progress achieved in quantum simulations of …

Three-dimensional higher-order topological semimetals in crystalline systems exhibit higher-
order Fermi arcs on one-dimensional hinges, challenging the conventional bulk-boundary …

Higher-order topological phases (HOTPs) hold gapped bulk bands and topological
boundary states localized in boundaries with codimension higher than one. In this paper, we …

Three-dimensional topological Dirac semimetal (DSM) is a vital state to explore topological
phases and phase transitions. However, its bulk-boundary correspondence is elusive. Here …

We review our most recent research on quantum transport, organizing the review according
to the intensity of the magnetic field and focus mostly on topological semimetals and …

Weyl semimetals are emerging to become a new class of quantum-material platform for
various novel phenomena. Especially, the Weyl orbit made from surface Fermi arcs and bulk …
