Nonreciprocity is necessary for robust dimensional reduction and strong responses in stochastic topological systems

A Nelson, E Tang - Physical Review B, 2024 - APS
Topological theory predicts the necessary conditions for robust dimensional reduction in a
host of quantum and classical systems. Models have recently been proposed for stochastic …

Boundary-sensitive Lindbladians and relaxation dynamics

X Feng, S Chen - Physical Review B, 2024 - APS
It is well known that non-Hermitian systems can be extremely sensitive to boundary
conditions owing to non-Hermitian skin effect (NHSE). Analogously, we investigate two …

Accelerated decay due to operator spreading in bulk-dissipated quantum systems

T Shirai, T Mori - Physical review letters, 2024 - APS
Markovian open many-body quantum systems display complicated relaxation dynamics. The
spectral gap of the Liouvillian characterizes the asymptotic decay rate towards the stationary …

T Sawada, K Sone, K Yokomizo, Y Ashida… - arXiv preprint arXiv …, 2024 - arxiv.org
Bulk-boundary correspondence is a fundamental principle in topological physics. In recent
years, there have been considerable efforts in extending the idea of geometry and topology …

Stochastic topological systems in arrays of optical tweezers under thermal activation

M Gao, N Li, X Chen, H Cai, H Hu - Applied Optics, 2024 - opg.optica.org
Topology has become important in understanding condensed matter physics and photonics,
such as the quantum Hall effect. Recently, interest has grown in applying topology to …

Topological phases in discrete stochastic systems

J Agudo-Canalejo, E Tang - arXiv preprint arXiv:2406.03925, 2024 - arxiv.org
Topological invariants have proved useful for analyzing emergent function as they
characterize a property of the entire system, and are insensitive to local details, disorder …

Hermitian and non-Hermitian topology in active matter

K Sone, K Yokomizo, K Kawaguchi… - arXiv preprint arXiv …, 2024 - arxiv.org
Self-propulsion is a quintessential aspect of biological systems, which can induce
nonequilibrium phenomena that have no counterparts in passive systems. Motivated by …
