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 …

Superconductivity and strong correlations in moiré flat bands

L Balents, CR Dean, DK Efetov, AF Young - Nature Physics, 2020 - nature.com

Majorana zero modes and topological quantum computation

SD Sarma, M Freedman, C Nayak - npj Quantum Information, 2015 - nature.com
We provide a current perspective on the rapidly develo** field of Majorana zero modes

Observation of fractional Chern insulators in a van der Waals heterostructure

EM Spanton, AA Zibrov, H Zhou, T Taniguchi… - Science, 2018 - science.org
Topologically ordered phases are characterized by long-range quantum entanglement and
fractional statistics rather than by symmetry breaking. First observed in a fractionally filled …

Tunable interacting composite fermion phases in a half-filled bilayer-graphene Landau level

AA Zibrov, C Kometter, H Zhou, EM Spanton… - Nature, 2017 - nature.com

Fractional charge and fractional statistics in the quantum Hall effects

DE Feldman, BI Halperin - Reports on Progress in Physics, 2021 - iopscience.iop.org
Quasiparticles with fractional charge and fractional statistics are key features of the fractional
quantum Hall effect. We discuss in detail the definitions of fractional charge and statistics …

Four-spin terms and the origin of the chiral spin liquid in Mott insulators on the triangular lattice

T Cookmeyer, J Motruk, JE Moore - Physical review letters, 2021 - APS
At strong repulsion, the triangular-lattice Hubbard model is described by s= 1/2 spins with
nearest-neighbor antiferromagnetic Heisenberg interactions and exhibits conventional 120° …

Particle-vortex duality of two-dimensional Dirac fermion from electric-magnetic duality of three-dimensional topological insulators

MA Metlitski, A Vishwanath - Physical Review B, 2016 - APS
Particle-vortex duality is a powerful theoretical tool that has been used to study bosonic
systems. Here, we propose an analogous duality for Dirac fermions in 2+ 1 dimensions. The …
