Monodomain Liquid Crystals of Two-Dimensional Sheets by Boundary-Free Sheargraphy

Nano-Micro Letters, 2022
Highlights Monodomain liquid crystals of graphene oxide over 30 cm is realized by boundary-free sheargraphy. The achieved monodomain liquid crystals have bidirectional sheet ordering, exhibiting unique optical, rheological, and conductive properties ...

The boundaries of 2+1D fermionic topological orders [PDF]

arXiv, 2022
$2+1$D bosonic topological orders can be characterized by the $S,T$ matrices that encode the statistics of topological excitations. In particular, the $S,T$ matrices can be used to systematically obtain the gapped boundaries of bosonic topological orders. Such an approach, however, does not naively apply to fermionic topological orders (FTOs).

Flux Confinement in Mesoscopic Superconductors

, 1998
We report on flux confinement effects in superconducting submicron line, loop and dot structures. The main idea of our study was to vary the boundary conditions for confinement of the superconducting condensate by taking samples of different topology and,

Extraction of Connected Region Boundary in Multidimensional Images

Image Processing On Line, 2014
This paper presents an algorithm to extract the boundary of a connected region(s) using classical topology definitions. From a given adjacency definition, the proposed method is able to extract the boundary of an object in a generic way, independently of

Chiral Dirac superconductors: Second-order and boundary-obstructed topology

Physical Review Research, 2020
We analyze the topological properties of a chiral p+ip superconductor for a two-dimensional metal and semimetal with four Dirac points. Such a system has been proposed to realize second-order topological superconductivity and host corner Majorana modes ...

Localization and traces in open-closed topological Landau-Ginzburg models

, 2004
We reconsider the issue of localization in open-closed B-twisted Landau-Ginzburg models with arbitrary Calabi-Yau target. Through careful analsysis of zero-mode reduction, we show that the closed model allows for a one-parameter family of localization ...

Topological boundaries of representations and coideals

Advances in Mathematics
For a locally compact quantum group $\mathbb{G}$, a (left) coideal is a (left) $\mathbb{G}$-invariant von Neumann subalgebra of $L^\infty(\mathbb{G})$. We introduce and analyze various generalizations of amenability and coamenability to coideals of discrete and compact quantum groups.
