Topological Blocking in Quantum Quench Dynamics [PDF]
, 2014 We study the non-equilibrium dynamics of quenching through a quantum critical point in topological systems, focusing on one of their defining features: ground state degeneracies and associated topological sectors.

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.

Discharging dynamics of topological batteries
Physical Review Research, 2020 Topological constraints have long been known to provide efficient mechanisms for localizing and storing energy across a range of length scales, from knots in DNA to turbulent plasmas.

Unveiling hidden topological phases of a one-dimensional Hadamard quantum walk [PDF]
, 2015 Quantum walks, whose dynamics is prescribed by alternating unitary coin and shift operators, possess topological phases akin to those of Floquet topological insulators, driven by a time-periodic field. While there is ample theoretical work on topological

Dynamically induced topological inflation
Physical Review D, 2023 We propose an inflation model in which the inflationary era is driven by the strong dynamics of $Sp(2)$ gauge theory. The quark condensation in the confined phase of $Sp(2)$ gauge theory generates the inflaton potential comparable to the energy of the thermal bath at the time of phase transition.

Observation of Anderson phase in a topological photonic circuit
Physical Review Research, 2022 Disordered systems play a central role in condensed matter physics, quantum transport, and topological photonics. It is commonly believed that a topological nontrivial phase would turn into a trivial phase where the transport vanishes under the effect of

The Regularizing Capacity of Metabolic Networks
, 2006 Despite their topological complexity almost all functional properties of metabolic networks can be derived from steady-state dynamics. Indeed, many theoretical investigations (like flux-balance analysis) rely on extracting function from steady states ...

Influence Maximization Dynamics and Topological Order on Erdös-Rényi Networks
Mathematics, 2023 This paper concerns the study of the linear threshold model in random networks, specifically in Erdös-Rényi networks. In our approach, we consider an activation threshold defined by the expected value for the node degree and the associated influence ...

Ultrafast Spin-To-Charge Conversion at the Surface of Topological Insulator Thin Films
, 2018 Strong spin-orbit coupling, resulting in the formation of spin-momentum-locked surface states, endows topological insulators with superior spin-to-charge conversion characteristics, though the dynamics that govern it have remained elusive.
