Topology and Signature Changes in Braneworlds [PDF]
It has been believed that topology and signature change of the universe can only happen accompanied by singularities, in classical, or instantons, in quantum, gravity.

Fermi surface topology and signature of surface Dirac nodes in LaBi
Novel topological state of matter is one of the rapidly growing fields in condensed matter physics research in recent times. While these materials are fascinating from the aspect of fundamental physics of relativistic particles, their exotic transport ...

Adapted topologies and higher rank signatures [PDF]
The topology of weak convergence does not account for the growth of information over time that is captured in the filtration of an adapted stochastic process. For example, two adapted stochastic processes can have very similar laws but give completely different results in applications such as optimal stopping, queuing theory, or stochastic programming.

Circuit topology analysis of cellular genome reveals signature motifs, conformational heterogeneity, and scaling [PDF]
Summary: Reciprocal regulation of genome topology and function is a fundamental and enduring puzzle in biology. The wealth of data provided by Hi-C libraries offers the opportunity to unravel this relationship.

Signature of topology via heat transfer analysis in the Su–Schrieffer–Heeger (SSH) model [PDF]
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.

Dynamical Determination of the Metric Signature in Spacetime of Nontrivial Topology [PDF]
The formalism of Greensite for treating the spacetime signature as a dynamical degree of freedom induced by quantum fields is considered for spacetimes with nontrivial topology of the kind ${\bf R}^{D-1} \times {\bf T}^1$, for varying $D$.

Discovery of higher-order topological insulators using the spin Hall conductivity as a topology signature [PDF]
The discovery and realization of topological insulators, a phase of matter which hosts metallic boundary states when the d-dimension insulating bulk is confined to (d − 1)-dimensions, led to several potential applications.

Classical Signature Change in the Black Hole Topology [PDF]
Investigations of classical signature change have generally envisaged applications to cosmological models, usually a Friedmann-Lemaitre-Robertson-Walker model.

Signatures in algebra, topology and dynamics
We survey the 19th century development of the signature of a quadratic form, and the applications in the 20th and 21st century to the topology of manifolds and dynamical systems. Version 2 is an expanded and corrected version of Version 1, including an Appendix by the second named author "Algebraic L-theory of rings with involution and the localization

Inter-chromosomal contacts demarcate genome topology along a spatial gradient [PDF]
Non-homologous chromosomal contacts (NHCCs) between different chromosomes participate considerably in gene and genome regulation. Due to analytical challenges, NHCCs are currently considered as singular, stochastic events, and their extent and ...
