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 …

Quantum criticality under decoherence or weak measurement

JY Lee, CM Jian, C Xu - PRX quantum, 2023 - APS
Decoherence inevitably happens when a quantum state is exposed to its environment,
which can affect quantum critical points (QCPs) in a nontrivial way. As was pointed out in the …

What's Done Cannot Be Undone: TASI Lectures on Non-Invertible Symmetry

SH Shao - arXiv preprint arXiv:2308.00747, 2023 - arxiv.org
We survey recent developments in a novel kind of generalized global symmetry, the non-
invertible symmetry, in diverse spacetime dimensions. We start with several different but …

Theta, time reversal and temperature

D Gaiotto, A Kapustin, Z Komargodski… - Journal of High Energy …, 2017 - Springer
A bstract SU (N) gauge theory is time reversal invariant at θ= 0 and θ= π. We show that at θ=
π there is a discrete't Hooft anomaly involving time reversal and the center symmetry. This …

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 …

Disorder operator and Rényi entanglement entropy of symmetric mass generation

ZH Liu, Y Da Liao, G Pan, M Song, J Zhao, W Jiang… - Physical Review Letters, 2024 - APS
The “symmetric mass generation”(SMG) quantum phase transition discovered in recent
years has attracted great interest from both condensed matter and high energy theory …

Paired states of fermions in two dimensions with breaking of parity and time-reversal symmetries and the fractional quantum Hall effect

N Read, D Green - Physical Review B, 2000 - APS
We analyze pairing of fermions in two dimensions for fully gapped cases with broken parity
(P) and time reversal (T), especially cases in which the gap function is an orbital angular …

An introduction to lattice gauge theory and spin systems

JB Kogut - Reviews of Modern Physics, 1979 - APS
This article is an interdisciplinary review of lattice gauge theory and spin systems. It
discusses the fundamentals, both physics and formalism, of these related subjects. Spin …

Quantum mechanics of fractional-spin particles

F Wilczek - Physical review letters, 1982 - APS
Composites formed from charged particles and vortices in (2+ 1)-dimensional models, or flux
tubes in three-dimensional models, can have any (fractional) angular momentum. The …
