Infernal and exceptional edge modes: non-Hermitian topology beyond the skin effect
JPhys Materials, 2023 The classification of point gap topology in all local non-Hermitian (NH) symmetry classes has been recently established. However, many entries in the resulting periodic table have only been discussed in a formal setting and still lack a physical ...

Topological boundaries of covariant representations
MATHEMATICA SCANDINAVICA, 2023 We associate a boundary $\mathcal B_{\pi ,u}$ to each covariant representation $(\pi ,u,H)$ of a $C^*$-dynamical system $(G,A,\alpha )$ and study the action of $G$ on $\mathcal B_{\pi ,u}$ and its amenability properties. We relate rigidity properties of traces on the associated crossed product $C^*$-algebra to faithfulness of the action of the group on

Degeneration of Heegaard genus, a survey [PDF]
, 2007 We survey known (and unknown) results about the behavior of Heegaard genus of 3-manifolds constructed via various gluings. The constructions we consider are (1) gluing together two 3-manifolds with incompressible boundary, (2) gluing together the ...

Entanglement entropy of topological orders with boundaries [PDF]
Journal of High Energy Physics, 2018 Abstract In this paper we explore how non trivial boundary conditions could influence the entanglement entropy in a topological order in 2+1 dimensions. Specifically we consider the special class of topological orders describable by the quantum double.

A Novel Mesh Quality Improvement Method for Boundary Elements
Journal of Applied Mathematics, 2012 In order to improve the boundary mesh quality while maintaining the essential characteristics of discrete surfaces, a new approach combining optimization-based smoothing and topology optimization is developed. The smoothing objective function is modified,

Dynamical confinement in bosonized QCD2
, 1992 In the bosonized version of two dimensional theories non trivial boundary conditions (topology) play a crucial role. They are inevitable if one wants to describe non singlet states. In abelian bosonization, color is the charge of a topological current in

A level-set-based topology optimisation of carpet cloaking devices with the boundary element method
Mechanical Engineering Journal, 2016 We investigate a topology optimisation based on the level set method for a design problem of carpet cloaking devices. In topology optimisation of carpet cloaking devices, we need to calculate the electromagnetic response in a semi-infinite domain. We use
