Matrix product states and projected entangled pair states: Concepts, symmetries, theorems

JI Cirac, D Perez-Garcia, N Schuch, F Verstraete - Reviews of Modern Physics, 2021 - APS
The theory of entanglement provides a fundamentally new language for describing
interactions and correlations in many-body systems. Its vocabulary consists of qubits and …

Non-invertible symmetries and LSM-type constraints on a tensor product Hilbert space

N Seiberg, S Seifnashri, SH Shao - SciPost Physics, 2024 - scipost.org
We discuss the exact non-invertible Kramers-Wannier symmetry of 1+ 1d lattice models on a
tensor product Hilbert space of qubits. This symmetry is associated with a topological defect …

Higher categorical symmetries and gauging in two-dimensional spin systems

C Delcamp, A Tiwari - SciPost Physics, 2024 - scipost.org
We present a framework to systematically investigate higher categorical symmetries in two-
dimensional spin systems. Though exotic, such generalised symmetries have been shown …

Sequential quantum circuits as maps between gapped phases

X Chen, A Dua, M Hermele, DT Stephen… - Physical Review B, 2024 - APS
Finite-depth quantum circuits preserve the long-range entanglement structure in quantum
states and map between states within a gapped phase. To map between states of different …

Dualities in one-dimensional quantum lattice models: symmetric Hamiltonians and matrix product operator intertwiners

L Lootens, C Delcamp, G Ortiz, F Verstraete - PRX Quantum, 2023 - APS
We present a systematic recipe for generating and classifying duality transformations in one-
dimensional quantum lattice systems. Our construction emphasizes the role of global …

Dualities in one-dimensional quantum lattice models: topological sectors

L Lootens, C Delcamp, F Verstraete - PRX Quantum, 2024 - APS
It has been a long-standing open problem to construct a general framework for relating the
spectra of dual theories to each other. Here, we solve this problem for the case of one …

Lattice realizations of topological defects in the critical (1+ 1)-d three-state Potts model

M Sinha, F Yan, L Grans-Samuelsson, A Roy… - Journal of High Energy …, 2024 - Springer
A bstract Topological/perfectly-transmissive defects play a fundamental role in the analysis
of the symmetries of two dimensional conformal field theories (CFTs). In the present work …

Critical lattice model for a Haagerup conformal field theory

R Vanhove, L Lootens, M Van Damme, R Wolf… - Physical review …, 2022 - APS
We use the formalism of strange correlators to construct a critical classical lattice model in
two dimensions with the Haagerup fusion category H 3 as input data. We present compelling …

Exact emergent higher-form symmetries in bosonic lattice models

SD Pace, XG Wen - Physical Review B, 2023 - APS
Although condensed matter systems usually do not have higher-form symmetries, we show
that, unlike 0-form symmetry, higher-form symmetries can emerge as exact symmetries at …

L Chen, K Ji, H Zhang, C Shen, R Wang, X Zeng… - Physical Review X, 2024 - APS
We show that the path integral of conformal field theories in D dimensions (CFT D) can be
constructed by solving for eigenstates of a renormalization group (RG) operator following …
