Analog of Topological Entanglement Entropy for Mixed States

PRX Quantum
We propose the convex-roof extension of quantum conditional mutual information (“co(QCMI)”) as a diagnostic of topological order in a mixed state. We focus primarily on topological states subjected to local decoherence, and employ the Levin-Wen scheme to

Fremlin tensor product respects the unbounded convergences

, 2023
Suppose $\Sigma$ is a topological space and $S(\Sigma)$ is the vector lattice of all continuous real-valued functions defined on open dense subsets of $\Sigma$. In this paper, we establish some lattice and topological aspects of $S(\Sigma)$.

Hom functor and the associativity of tensor products of modules for vertex operator algebras [PDF]

arXiv, 1996
We give a new, construction-free proof of the associativity of tensor product for modules for rational vertex operator algebras under certain convergence conditions.

Chern classes of tensor products [PDF]

arXiv, 2010
We prove explicit formulas for Chern classes of tensor products of vector bundles, with coefficients given by certain universal polynomials in the ranks of the two bundles.

Geometry of Topological Defects of Two-dimensional Sigma Models [PDF]

, 2010
A topological defect separating a pair of two-dimensional CFTs is a codimension one interface along which all components of the stress-energy tensor glue continuously.

The Boardman-Vogt tensor product of operadic bimodules [PDF]

arXiv, 2013
We define and study a lift of the Boardman-Vogt tensor product of operads to bimodules over operads.

Anomaly inflow for CSS and fractonic lattice models and dualities via cluster state measurement

SciPost Physics
Calderbank-Shor-Steane (CSS) codes are a class of quantum error correction codes that contains the toric code and fracton models. A procedure called foliation defines a cluster state for a given CSS code.

The Fredholm index for operators of tensor product type [PDF]

arXiv, 2018
We consider bisingular pseudodifferential operators which are pseudodifferential operators of tensor product type. These operators are defined on the product manifold $M_1 \times M_2$, for closed manifolds $M_1$ and $M_2$. We prove a topological index theorem of product type. In addition, we show that the Fredholm index of elliptic bisingular operators

On Chern classes of tensor products of vector bundles [PDF]

arXiv, 2019
We present two formulas for Chern classes of the tensor product of two vector bundles. In the first formula we consider a matrix containing Chern classes of the first bundle and we take a polynomial of this matrix with Chern classes of the second bundle as coefficients.
