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

Disorder, ubiquitously present in realistic structures, is generally thought to disturb the
performance of analog wave devices, as it often causes strong multiple scattering effects that …

The winding number has been widely used as an invariant for diagnosing topological
phases in one-dimensional chiral-symmetric systems. We put forward a real-space …

The disorder effects on higher-order topological phases in periodic systems have attracted
much attention. However, in aperiodic systems, such as quasicrystalline systems, the …

Non-Hermiticity from nonreciprocal hoppings has recently been shown to induce exotic non-
Hermitian phenomena. Here, we study a class of nonreciprocal quasicrystal …

We investigate localization and topological properties of a dimerized Kitaev chain with p-
wave superconducting correlations and a quasiperiodically modulated chemical potential …

Recent research on disorder effects in topological phases in quasicrystalline systems has
received much attention. In this work, by numerically computing the (spin) Bott index and the …

The dynamics of the geometric phase are studied in inhomogeneous quantum spin chains
after a quench. Analytic expressions of the Pancharatnam geometric phase (PGP) are …

The quest for the topological phases of matter in an aperiodic system has been greatly
developed recently. Here we investigate the effects of disorder on topological phases of a …

Recently, topological phases in non-Hermitian systems have attracted great attention. In
most of these works, disorders are added to the chemical potential or hopping term and the …
