Spin liquids in geometrically perfect triangular antiferromagnets

Y Li, P Gegenwart, AA Tsirlin - Journal of Physics: Condensed …, 2020 - iopscience.iop.org
The cradle of quantum spin liquids, triangular antiferromagnets show strong proclivity to
magnetic order and require deliberate tuning to stabilize a spin-liquid state. In this brief …

Quantum phase transitions

S Sachdev - Physics world, 1999 - iopscience.iop.org
NATURE abounds with phase transitions. The boiling and freezing of water are everyday
examples of phase transitions, as are more exotic processes such as superconductivity and …

Spin liquid nature in the Heisenberg triangular antiferromagnet

Y Iqbal, WJ Hu, R Thomale, D Poilblanc, F Becca - Physical Review B, 2016 - APS
We investigate the spin-1 2 Heisenberg model on the triangular lattice in the presence of
nearest-neighbor J 1 and next-nearest-neighbor J 2 antiferromagnetic couplings. Motivated …

Order versus disorder in the quantum Heisenberg antiferromagnet on the kagomé lattice using exact spectra analysis

P Lecheminant, B Bernu, C Lhuillier, L Pierre… - Physical Review B, 1997 - APS
A group-symmetry analysis of the low-lying levels of the spin-1/2 kagomé Heisenberg
antiferromagnet is performed for small samples up to N= 27. This approach allows one to …

Gapless spin-liquid phase in an extended spin 1/2 triangular Heisenberg model

R Kaneko, S Morita, M Imada - Journal of the Physical Society of …, 2014 - journals.jps.jp
We numerically study the Heisenberg models on triangular lattices by extending it from the
simplest equilateral lattice with only the nearest-neighbor exchange interaction. We show …

Kagome antiferromagnet: A chiral topological spin liquid?

L Messio, B Bernu, C Lhuillier - Physical review letters, 2012 - APS
Inspired by the recent discovery of a new instability towards a chiral phase of the classical
Heisenberg model on the kagome lattice, we propose a specific chiral spin liquid that …

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 …

Lattice symmetries and regular magnetic orders in classical frustrated antiferromagnets

L Messio, C Lhuillier, G Misguich - Physical Review B—Condensed Matter and …, 2011 - APS
We consider some classical and frustrated lattice spin models with global O (3) spin
symmetry. No general analytical method to find a ground state exists when the spin …

Emergence of classical magnetic order from anderson towers: Quantum darwinism in action

OM Sotnikov, EA Stepanov, MI Katsnelson, F Mila… - Physical Review X, 2023 - APS
Environment is assumed to play a negative role in quantum mechanics, destroying the
coherence in a quantum system and, thus, randomly changing its state. However, for a …
