Signature of topology via heat transfer analysis in the Su–Schrieffer–Heeger (SSH) model
New Journal of Physics, 2023 In this work, we explore how thermodynamics can be a potential tool for identifying the topological phase transition. Specifically, we focus on a one-dimensional Su–Schrieffer–Heeger (SSH) chain sandwiched between two fermionic baths.

Experimental signature of layer skyrmions and implications for band topology in twisted WSe2 bilayers [PDF]
Nature PhysicsTwisted homobilayers of transition-metal dichalcogenides have been established as an ideal platform for studying strong correlation phenomena, as exemplified by the recent discovery of fractional Chern insulator states in twisted MoTe2, as well as Chern ...

Signature of the Ground-State Topology in the Low-Temperature Dynamics of Spin Glasses [PDF]
Physical Review Letters, 2006 We numerically address the issue of how the ground-state topology is reflected in the finite temperature dynamics of the +/-J Edwards-Anderson spin glass model. In this system a careful study of the ground-state configurations allows us to classify spins

The topology and geometry of neural representations [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2023 Significance Characterizing the representations encoded in patterns of neural activity is key to understanding brain computation. Representational similarity analysis uses the geometry of neural population response patterns to compare representations ...

Observation of interplay between phonon chirality and electronic band topology [PDF]
Science Advances, 2022 The recently demonstrated chiral modes of lattice motion carry angular momentum and therefore directly couple to magnetic fields. Notably, their magnetic moments are predicted to be strongly influenced by electronic contributions.

Cosmic topology. Part I. Limits on orientable Euclidean manifolds from circle searches [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 The Einstein field equations of general relativity constrain the local curvature at every point in spacetime, but say nothing about the global topology of the Universe. Cosmic microwave background anisotropies have proven to be the most powerful probe of

Graphic Groups, Graph Homomorphisms, and Graphic Group Lattices in Asymmetric Topology Cryptography
Entropy, 2023 Using asymmetric topology cryptography to encrypt networks on the basis of topology coding is a new topic of cryptography, which consists of two major elements, i.e., topological structures and mathematical constraints.

The signature and cusp geometry of hyperbolic knots [PDF]
Geometry & Topology, 2021 We introduce a new real-valued invariant called the natural slope of a hyperbolic knot in the 3-sphere, which is defined in terms of its cusp geometry.
