Majorana Diagrammatics for Quantum Spin-1/2 Models
Thibault Noblet, Laura Messio, Riccardo Rossi
A diagrammatic formalism for lattices of 1/2 is developed. It is based on an unconstrained mapping between spin and Majorana operators. This allows the use of standard tools of dia…
Is Herbertsmithite far from an ideal antiferromagnet? Ab-initio answer including in-plane Dzyaloshinskii-Moriya interactions and coupling with extra-plane impurities
Flaurent Heully-Alary, Nadia Ben Amor, Nicolas Suaud +3
Herbertsmithite is known as the archetype of a S=1/2 nearest-neighbor Heisenberg antiferromagnet on the Kagomé lattice, theoretically presumed to be a quantum gapless spin liquid.…
High temperature series expansions of S = 1/2 Heisenberg spin models: algorithm to include the magnetic field with optimized complexity
Laurent Pierre, Bernard Bernu, Laura Messio
This work presents an algorithm for calculating high temperature series expansions (HTSE) of Heisenberg spin models with spin in the thermodynamic limit. This algorithm acc…
Finite-temperature phase transitions in three-dimensional Heisenberg magnets from high-temperature series expansions
M. G. Gonzalez, B. Bernu, L. Pierre +1
Many frustrated spin models on three-dimensional (3D) lattices are currently being investigated, both experimentally and theoretically, and develop new types of long-range orders i…
Non-linear magnons and exchange Hamiltonians of delafossite proximate quantum spin liquids
A. O. Scheie, Y. Kamiya, Hao Zhang +20
Quantum spin liquids (QSL) are theoretical states of matter with long-range entanglement and exotic quasiparticles. However, they generally elude quantitative theory, rendering the…
Ground-state and thermodynamic properties of the spin- Heisenberg model on the anisotropic triangular lattice
Matías G. Gonzalez, Bernard Bernu, Laurent Pierre +1
The spin- triangular lattice antiferromagnetic Heisenberg model has been for a long time the prototypical model of magnetic frustration. However, only very recently this m…
