Frustration and entanglement in the spin--orbital model on a triangular lattice: valence--bond and generalized liquid states
Bruce Normand, Andrzej M. Oles
We consider the spin--orbital model for a magnetic system with singly occupied but triply degenerate orbitals coupled into a planar, triangular lattice, as would be exempl…
Quantum Magnets under Pressure: Controlling Elementary Excitations in TlCuCl3
Ch. Rüegg, B. Normand, M. Matsumoto +7
We follow the evolution of the elementary excitations of the quantum antiferromagnet TlCuCl3 through the pressure-induced quantum critical point, which separates a dimer-based quan…
Exchange constants and spin dynamics in Mn12-acetate
A. Honecker, N. Fukushima, B. Normand +2
We have obtained new inelastic neutron scattering (INS) data for the molecular magnet Mn12-acetate which exhibit at least six magnetic peaks in the energy range 5-35 meV. These are…
Exchange Interactions and High-Energy Spin States in Mn_12-acetate
G. Chaboussant, A. Sieber, S. Ochsenbein +5
We perform inelastic neutron scattering measurements on the molecular nanomagnet Mn_12-acetate to measure the excitation spectrum up to 45meV (500K). We isolate magnetic excitation…
Quantum Antiferromagnets in a Magnetic Field
Daniel Loss, B. Normand
Motivated by recent experiments on low-dimensional quantum magnets in applied magnetic fields, we present a theoretical analysis of their properties based on the nonlinear sigma mo…
