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 ...

Dynamical signatures of symmetry protected topology following symmetry breaking

open access: yesPhysical Review Research, 2021
We investigate topological signatures in the short-time nonequilibrium dynamics of symmetry protected topological (SPT) systems starting from initial states which break a protecting symmetry.

Topological heterogeneity and evaporation dynamics of irregular water droplets

open access: yesScientific Reports, 2021
Water droplets sitting between wires are ubiquitous in nature and industry, often showing irregular (non-spherical) droplet shapes. To understand their topological singularity and evaporation mechanism, measuring volume changes of irregular water ...

Modeling internet topology dynamics [PDF]

open access: yesACM SIGCOMM Computer Communication Review, 2008
Despite the large number of papers on network topology modeling and inference, there still exists ambiguity about the real nature of the Internet AS and router level topology. While recent findings have illustrated the inaccuracies in maps inferred from BGP peering and traceroute measurements, existing topology models still produce static topologies ...

Fixed Points and Dynamic Topological Phenomena in a Parity-Time-Symmetric Quantum Quench

open access: yesiScience, 2019
Summary: We identify dynamic topological phenomena such as dynamic Chern numbers and dynamic quantum phase transitions in quantum quenches of the non-Hermitian Su-Schrieffer-Heeger Hamiltonian with parity-time (PT) symmetry.

Topological origin of quantized transport in non-Hermitian Floquet chains

open access: yesPhysical Review Research, 2020
We show that non-Hermiticity enables topological phases with unidirectional transport in one-dimensional Floquet chains. The topological signatures of these phases are noncontractible loops in the spectrum of the Floquet propagator that are separated by ...

Unified characterization for higher-order topological phase transitions

open access: yesPhysical Review Research, 2023
Higher-order topological phase transitions (HOTPTs) are associated with closing either the bulk energy gap (type-I) or boundary energy gap (type-II) without changing symmetry, and conventionally, both transitions are captured in real space and ...

Braiding Dynamics in Active Nematics

open access: yesFrontiers in Physics, 2022
In active matter systems, energy consumed at the small scale by individual agents gives rise to emergent flows at large scales. For 2D active nematic microtubule (ANMT) systems, these flows are largely characterized by the dynamics of mobile defects in ...

Aspects of Topological String Theory [PDF]

open access: yes, 2008
Two aspects of the topological string and its applications are considered in this thesis. Firstly, non-perturbative contributions to the OSV conjecture relating four-dimensional extremal black holes and the closed topological string partition function ...

On the Topological Dynamics of Dynamical Manifolds and Their Fundamental Group

open access: yesJournal of Mathematics, 2021
The paper aims to deduce the relation between the category of topology and algebra from viewpoint of geometry and dynamical system. We introduce and define a dynamical manifold as a manifold associated with a time parameter.
