Non-perturbative methodologies for low-dimensional strongly-correlated systems: From non-abelian bosonization to truncated spectrum methods

AJA James, RM Konik, P Lecheminant… - Reports on Progress …, 2018 - iopscience.iop.org
We review two important non-perturbative approaches for extracting the physics of low-
dimensional strongly correlated quantum systems. Firstly, we start by providing a …

A short introduction to topological quantum computation

V Lahtinen, J Pachos - SciPost Physics, 2017 - scipost.org
This review presents an entry-level introduction to topological quantum computation--
quantum computing with anyons. We introduce anyons at the system-independent level of …

SU (4) chiral spin liquid, exciton supersolid, and electric detection in moiré bilayers

YH Zhang, DN Sheng, A Vishwanath - Physical review letters, 2021 - APS
We propose a moiré bilayer as a platform where exotic quantum phases can be stabilized
and electrically detected. Moiré bilayers consist of two separate moiré superlattice layers …

Quantum Electrodynamics in Dimensions as the Organizing Principle of a Triangular Lattice Antiferromagnet

A Wietek, S Capponi, AM Läuchli - Physical Review X, 2024 - APS
Quantum electrodynamics in 2+ 1 dimensions (QED 3) has been proposed as a critical field
theory describing the low-energy effective theory of a putative algebraic Dirac spin liquid or …

Chiral spin liquid and quantum criticality in extended Heisenberg models on the triangular lattice

A Wietek, AM Läuchli - Physical Review B, 2017 - APS
We investigate the J 1-J 2 Heisenberg model on the triangular lattice with an additional
scalar chirality term and show that a chiral spin liquid is stabilized in a sizable region of the …

Exact Diagonalization of Fermi-Hubbard Models

T Botzung, P Nataf - Physical Review Letters, 2024 - APS
We show how to perform exact diagonalizations of SU (N) Fermi-Hubbard models on L-site
clusters separately in each irreducible representation (irrep) of SU (N). Using the …

Doping the chiral spin liquid: Topological superconductor or chiral metal

XY Song, A Vishwanath, YH Zhang - Physical Review B, 2021 - APS
We point out that there are two different chiral spin liquid states on the triangular lattice and
discuss the conducting states that are expected on doping them. These states labeled CSL1 …

Chiral Spin Liquid on the Square Lattice: A View from Symmetric Projected Entangled Pair States

JY Chen, S Capponi, A Wietek, M Mambrini… - Physical Review Letters, 2020 - APS
Quantum spin liquids can be faithfully represented and efficiently characterized within the
framework of projected entangled pair states (PEPS). Guided by extensive exact …

Emergence of Competing Orders and Possible Quantum Spin Liquid in Fermions

XJ Yu, SH Shi, L Xu, ZX Li - Physical Review Letters, 2024 - APS
In the past few decades, tremendous efforts have been made toward understanding the
exotic physics emerging from competition between various ordering tendencies in strongly …

Abelian chiral spin liquids on the square lattice

JY Chen, JW Li, P Nataf, S Capponi, M Mambrini… - Physical Review B, 2021 - APS
In the physics of the fractional quantum Hall (FQH) effect, a zoo of Abelian topological
phases can be obtained by varying the magnetic field. Aiming to reach the same …
