Recently, topolectrical circuits (TECs) boom in studying the topological states of matter. The
resemblance between circuit Laplacians and tight-binding models in condensed matter …

Higher-order Weyl semimetals are a family of recently predicted topological phases
simultaneously showcasing unconventional properties derived from Weyl points, such as …

Inverse Anderson transitions, where the flat-band localization is destroyed by disorder, have
been wildly investigated in quantum and classical systems in the presence of Abelian gauge …

Topological phases of matter have remained an active area of research in the last few
decades. Periodic driving is a powerful tool for enriching such exotic phases, leading to …

Bound states in the continuum (BICs), which are spatially localized states with energies lying
in the continuum of extended modes, have been widely investigated in both quantum and …

We theoretically investigate the engineering of two-dimensional second-order topological
insulators with corner states by coupling two first-order topological insulators. We find that …

The Chern insulator, as the most prominent topological state of matter, is characterized by
the Chern number C, which in principle can take any integer values. So far, most realizations …

Topological flat bands, which are regarded as the cornerstone of various topological states
induced by the many-body interaction, have aroused great interest in the fields of physics …

The Wilson fermion (WF) is a fundamental particle in the theory of quantum
chromodynamics. Theoretical calculations have shown that the WF with a half skyrmion …

Square-root topology describes models whose topological properties can be revealed upon
squaring the Hamiltonian, which produces their respective parent topological insulators …
