Topological Sectors and a Dichotomy in Conformal Field Theory

, 2004
Let A be a local conformal net of factors on the circle with the split property. We provide a topological construction of soliton representations of the tensor product of n copies of A, that restrict to true representations of subnet inviant under cyclic

Stretching‐Orientation Reinforced Double Network Solvent‐Free Eutectic Gels for Ultrarobust, Flexible Human‐Machine Interaction Devices

Advanced Functional Materials, EarlyView.
This work develops an ultrarobust, flexible, and solvent‐free eutectic gel featuring stretch‐induced orientation. Overcoming hydrogel limitations, the gel achieves record toughness (133.86 MJ m−3) while integrating strain/temperature/capacitive sensing.

Disentangling Interacting Symmetry-Protected Phases of Fermions in Two Dimensions

Physical Review X, 2019
We construct fixed point lattice models for group supercohomology symmetry-protected topological phases of fermions (2+1)D. A key feature of our approach is to construct finite depth circuits of local unitaries that explicitly build the ground states ...

Deterministic Constant-Depth Preparation of the AKLT State on a Quantum Processor Using Fusion Measurements

PRX Quantum, 2023
The ground state of the spin-1 Affleck, Kennedy, Lieb, and Tasaki (AKLT) model is a paradigmatic example of both a matrix product state and a symmetry-protected topological phase and additionally holds promise as a resource state for measurement-based ...

Noncommutative topological entropy of endomorphisms of Cuntz algebras II [PDF]

, 2010
A study of noncommutative topological entropy of gauge invariant endomorphisms of Cuntz algebras began in our earlier work with Joachim Zacharias is continued and extended to endomorphisms which are not necessarily of permutation type.

Engineering Topographical Cues to Enhance Neural Regeneration in Spinal Cord Injury: Overcoming Challenges and Advancing Therapies

Advanced Functional Materials, EarlyView.
Spinal cord injury (SCI) poses significant challenges for regeneration due to a series of secondary injury mechanisms. How to use biomaterial approach to target the failed regeneration after SCI remains a critical challenge. This review systematically evaluates current strategies to optimize biomaterial topographies for neurite outgrowth, axonal ...

A low-rank approximation of tensors and the topological group structure of invertible matrices

Учёные записки Казанского университета: Серия Физико-математические науки, 2018
By a tensor we mean an element of the tensor product of vector spaces over a field. Up to a choice of bases in factors of tensor products, every tensor may be coordinatized, i.e., represented as an array consisting of numbers.

Characterizing Matrix-Product States and Projected Entangled-Pair States Preparable via Measurement and Feedback

PRX Quantum
Preparing long-range entangled states poses significant challenges for near-term quantum devices. It is known that measurement and feedback (MF) can aid this task by allowing the preparation of certain paradigmatic long-range entangled states with only ...

Quantum error-detection at low energies

Journal of High Energy Physics, 2019
Motivated by the close relationship between quantum error-correction, topological order, the holographic AdS/CFT duality, and tensor networks, we initiate the study of approximate quantum error-detecting codes in matrix product states (MPS).

Geometric Structures in Tensor Representations (Final Release) [PDF]

, 2015
The main goal of this paper is to study the geometric structures associated with the representation of tensors in subspace based formats. To do this we use a property of the so-called minimal subspaces which allows us to describe the tensor ...
