Non-Bloch quench dynamics

open access: yesPhysical Review Research, 2021
We study the quench dynamics of non-Hermitian topological models with non-Hermitian skin effects. Adopting the non-Bloch band theory and projecting quench dynamics onto the generalized Brillouin zone, we find that emergent topological structures, in the ...

Topological optical parametric oscillation

open access: yesNanophotonics, 2022
Topological insulators possess protected boundary states which are robust against disorders and have immense implications in both fermionic and bosonic systems.

Category Theory for Autonomous and Networked Dynamical Systems

open access: yesEntropy, 2019
In this discussion paper we argue that category theory may play a useful role in formulating, and perhaps proving, results in ergodic theory, topogical dynamics and open systems theory (control theory). As examples, we show how to characterize Kolmogorov&

Topological resonances in a Möbius ring resonator

open access: yesCommunications Physics, 2023
A Möbius strip, fascinating for its unique topological property of being a one-side nonorientable surface, has inspired mathematicians, physicists, engineers, and artists for many centuries.

Quantum Dynamical Characterization and Simulation of Topological Phases With High-Order Band Inversion Surfaces

open access: yesPRX Quantum, 2021
How to characterize topological quantum phases is a fundamental issue in the broad field of topological matter. From a dimension reduction approach, we propose the concept of high-order band inversion surfaces (BISs), which enable the optimal schemes to ...

DEFINABLE TOPOLOGICAL DYNAMICS [PDF]

open access: yesThe Journal of Symbolic Logic, 2017
AbstractFor a groupGdefinable in a first order structureMwe develop basic topological dynamics in the category of definableG-flows. In particular, we give a description of the universal definableG-ambit and of the semigroup operation on it. We find a natural epimorphism from the Ellis group of this flow to the definable Bohr compactification ofG, that ...

Effects of spin symmetry breaking in topological insulators [PDF]

open access: yes, 2015
Topological insulators are one of the most thoroughly investigated systems in condensed matter physics over the last years. In these systems, a prominent role is inevitably taken by time-reversal symmetry, which leads to Kramers theorem and symmetry ...

Topological Analysis of Molecular Dynamics Simulations using the Euler Characteristic

open access: yes, 2022
Molecular dynamics (MD) simulations are used in diverse scientific and engineering fields such as drug discovery, materials design, separations, biological systems, and reaction engineering. These simulations generate highly complex datasets that capture

Topological dynamics on hyperspaces

open access: yesApplied General Topology, 2010
In this paper we wish to relate the dynamics of the base map to the dynamics of the induced map. In the process, we obtain conditions on the endowed hyperspace topology under which the chaotic behaviour of the map on the base space is inherited by the ...
