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…
Semiclassical evidence of columnar order in the fully frustrated transverse field Ising model on the square lattice
Tommaso Coletta, Sergey E. Korshunov, Frédéric Mila
We investigate the zero-temperature phase diagram of the fully frustrated transverse field Ising model on the square lattice both in the classical limit and in the presence of quan…
Quantum stabilization of classically unstable plateau structures
T. Coletta, M. E. Zhitomirsky, F. Mila
Motivated by the intriguing report, in some frustrated quantum antiferromagnets, of magnetization plateaus whose simple collinear structure is {\it not} stabilized by an external m…
Evidence of columnar order in the fully frustrated transverse field Ising model on the square lattice
Sandro Wenzel, Tommaso Coletta, Sergey E. Korshunov +1
Using extensive classical and quantum Monte Carlo simulations, we investigate the ground-state phase diagram of the fully frustrated transverse field Ising model on the square latt…
Semiclassical approach to ground-state properties of hard-core bosons in two dimensions
Tommaso Coletta, Nicolas Laflorencie, Frédéric Mila
Motivated by some inconsistencies in the way quantum fluctuations are included beyond the classical treatment of hard-core bosons on a lattice in the recent literature, we revisit…
Phase diagram of the fully frustrated transverse-field Ising model on the honeycomb lattice
T. Coletta, J. -D. Picon, S. E. Korshunov +1
Motivated by the current interest in the quantum dimer model on the triangular lattice, we investigate the phase diagram of the closely related fully-frustrated transverse field Is…
