The topological protection of wave transport, originally observed in the context of the
quantum Hall effect in two-dimensional electron gases, has been shown to apply broadly to …

The explicit real-time propagation approach for time-dependent density functional theory
(RT-TDDFT) has increasingly become a popular first-principles computational method for …

Thouless pum** enables topological transport and the direct measurement of topological
invariants. So far, realizations of Thouless pum** rely on the adiabatic evolution of a …

Topological pumps have garnered substantial attention in physics. However, the
requirement for slow evolution speed to satisfy adiabaticity greatly restricts their application …

In many contexts, interaction between particles gives rise to emergent phenomena. An
example is the fractional quantum Hall effect, where the interaction between electrons leads …

We present a theoretical study and experimental realization of a system that is
simultaneously a four-dimensional (4D) Chern insulator and a higher-order topological …

Continuous and quantized transports are profoundly different. The latter is determined by the
global rather than local properties of a system, it exhibits unique topological features, and its …

One-dimensional topological pum** of matter waves in two overlaid optical lattices
moving with respect to each other is considered in the presence of attractive nonlinearity. It …

Constructing new topological materials is of vital interest for the development of robust
quantum applications. However, engineering such materials often causes technological …

Thouless pump provides robust ways to realize quantized transport of waves and particles,
and it casts the static 2D quantum Hall effect onto 1D dynamic systems where one of the …
