Thouless pumping and topology [PDF]

open access: yesNature Reviews Physics, 2022
Thouless pumping is a dynamical quantum effect that results in a quantized response of a many-body system. It stems from the topological properties of the band structure that emerge under a periodic drive in the adiabatic limit. This Review addresses the

Topological Insulators by Topology Optimization [PDF]

open access: yesPhysical Review Letters, 2019
An acoustic topological insulator (TI) is synthesized using topology optimization, a free material inverse design method. The TI appears spontaneously from the optimization process without imposing requirements on the existence of pseudo spin-1/2 states at the TI interface edge, or the Chern number of the topological phases. The resulting TI is passive;

Topology optimization of multi-scale structures: a review

open access: yesStructural And Multidisciplinary Optimization, 2021
Multi-scale structures, as found in nature (e.g., bone and bamboo), hold the promise of achieving superior performance while being intrinsically lightweight, robust, and multi-functional.

Topology and topological sequence entropy [PDF]

open access: yesScience China Mathematics, 2019
Let $X$ be a compact metric space and $T:X\longrightarrow X$ be continuous. Let $h^*(T)$ be the supremum of topological sequence entropies of $T$ over all subsequences of $\mathbb Z_+$ and $S(X)$ be the set of the values $h^*(T)$ for all continuous maps $T$ on $X$.

Higher-order band topology [PDF]

open access: yesNature Reviews Physics, 2020
A conventional topological insulator (TI) has gapped bulk states but gapless edge states. The emergence of the gapless edge states is dictated by the bulk topological invariant of the insulator and the preservation of relevant symmetries.

Asymptotic topology [PDF]

open access: yes, 1999
We establish some basic theorems in dimension theory and absolute extensor theory in the coarse category of metric spaces. Some of the statements in this category can be translated in general topology language by applying the Higson corona functor.
