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…
Chiral order emergence driven by quenched disorder
Coraline Letouzé, Pascal Viot, Laura Messio
Quenched disorder can destroy magnetic order, for example when a random field is applied in a 2-dimensional Ising model. Even when an order exists in the presence of quenched disor…
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.…
Derivation of the free energy, entropy and specific heat for planar Ising models: Application to Archimedean lattices and their duals
Laurent Pierre, Bernard Bernu, Laura Messio
The 2d ferromagnetic Ising model was solved by Onsager on the square lattice in 1944, and an explicit expression of the free energy density is presently available for some othe…
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…
