Semiclassical theory of the magnetization process of the triangular lattice Heisenberg model
Tommaso Coletta, Tamás Tóth, Karlo Penc +1
Motivated by the numerous examples of 1/3 magnetization plateaux in the triangular lattice Heisenberg an- tiferromagnet with spins ranging from 1/2 to 5/2, we revisit the semiclass…

Dynamical structure factors and excitation modes of the bilayer Heisenberg model
M. Lohöfer, T. Coletta, D. G. Joshi +4
Using quantum Monte Carlo simulations along with higher-order spin-wave theory, bond-operator and strong-coupling expansions, we analyse the dynamical spin structure factor of the…
