Braiding Dynamics in Active Nematics
Frontiers 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 ...

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

On the Topological Dynamics of Dynamical Manifolds and Their Fundamental Group
Journal 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.

Noncommutative Topological Dynamics. II [PDF]
Transactions of the American Mathematical Society, 1984 This part deals with almost periodic and weakly mixing C ∗ {C^ \ast } -flows, and with disjointness and weak disjointness of C ∗ {C^ \ast } -flows (flows on C ∗ {C^ \ast } -algebras).

Interaction-induced breakdown of chiral dynamics in the Su-Schrieffer-Heeger model
Physical Review Research, 2023 The effect of interparticle interactions on topological properties is difficult to experimentally probe and quantitatively characterize. For ultracold atomic systems, although topological phases and phenomena have been recently observed in various ...

Unusual spin dynamics in topological insulators [PDF]
, 2015 The dynamic spin susceptibility (DSS) has a ubiquitous Lorentzian form in conventional materials with weak spin orbit coupling, whose spectral width characterizes the spin relaxation rate.

Nature of vibrational eigenmodes in topologically disordered solids [PDF]
, 2002 We use a local projectional analysis method to investigate the effect of topological disorder on the vibrational dynamics in a model glass simulated by molecular dynamics. Evidence is presented that the vibrational eigenmodes in the glass are generically

Independence in topological and C*-dynamics [PDF]
, 2007 We develop a systematic approach to the study of independence in topological dynamics with an emphasis on combinatorial methods. One of our principal aims is to combinatorialize the local analysis of topological entropy and related mixing properties.
