Theoretical constraints for the magnetic-dimer transition in two-dimensional spin models
Leonardo Spanu, Federico Becca, Sandro Sorella
From general arguments, that are valid for spin models with sufficiently short-range interactions, we derive strong constraints on the excitation spectrum across a continuous phase…

Lattice effects on the spin dynamics in antiferromagnetic molecular rings
Leonardo Spanu, Alberto Parola
We investigate spin dynamics in antiferromagnetic (AF) molecular rings at finite temperature in the presence of spin-phonon (s-p) interaction. We derive a general expression for th…

Weakly frustrated two-dimensional Heisenberg antiferromagnets: thermodynamic properties from a non-perturbative approach
Leonardo Spanu, Alberto Parola
We analyze the thermodynamic properties of the spin-S two-dimensional quantum Heisenberg antiferromagnet on a square lattice with nearest and next-nearest neighbor couplings in the…
