Entanglement of valence-bond-solid state models on topological surfaces
Results in Physics, 2022 We investigated the scaling behaviors of entanglements on the two-leg ladder lattice structure implemented with Affleck–Kennedy–Lieb–Tasaki (AKLT) model on six types of topological surfaces, namely, torus, sphere, real projective plane, Klein bottle ...

The Second Hyper-Zagreb Coindex of Chemical Graphs and Some Applications
Journal of Chemistry, 2021 The second hyper-Zagreb coindex is an efficient topological index that enables us to describe a molecule from its molecular graph. In this current study, we shall evaluate the second hyper-Zagreb coindex of some chemical graphs. In this study, we compute

Algebraic Representation of Topologies on a Finite Set
Mathematics, 2022 Since the 1930s, topological counting on finite sets has been an interesting work so as to enumerate the number of corresponding order relations on the sets.

ARENS REGULARITY OF PROJECTIVE TENSOR PRODUCT
, 2021 In this paper, we study approximate identity properties, some propositions from Baker, Dales, Lau in general situations and we establish some relationships between the topological centers of module actions and factorization properties with some results ...

Boson condensation and instability in the tensor network representation of string-net states [PDF]
, 2018 The tensor network representation of many-body quantum states, given by local tensors, provides a promising numerical tool for the study of strongly correlated topological phases in two dimension. However, tensor network representations may be vulnerable

Hybrid Berezinskii-Kosterlitz-Thouless and Ising topological phase transition in the generalized two-dimensional XY model using tensor networks [PDF]
, 2020 In tensor network representation, the partition function of a generalized two-dimensional XY spin model with topological integer and half-integer vortex excitations is mapped to a tensor product of one-dimensional quantum transfer operator, whose ...

Invertible defects and isomorphisms of rational CFTs [PDF]
, 2010 Given two two-dimensional conformal field theories, a domain wall —or defect line— between them is called invertible if there is another defect with which it fuses to the identity defect.

Twisted string theory in anti-de Sitter space
Journal of High Energy Physics, 2020 We construct a string theory in three-dimensional anti-de Sitter space-time that is independent of the boundary metric. It is a topologically twisted theory of quantum gravity. We study string theories with an asymptotic N = 2 superconformal symmetry and

Fermionic projected entangled-pair states and topological phases [PDF]
, 2017 We study fermionic matrix product operator algebras and identify the associated algebraic data. Using this algebraic data we construct fermionic tensor network states in two dimensions that have non-trivial symmetry-protected or intrinsic topological ...
