Nonperturbative Semiclassical Spin Dynamics for Ordered Quantum Magnets
Hao Zhang, Tianyue Huang, Allen O. Scheie +7
In ordered quantum magnets where interactions between elementary excitations dominate over their kinetic energy, perturbative approaches often fail, making non-perturbative methods…
Microscopic Origin of Reduced Magnetic Order in a Frustrated Metal
X. Boraley, O. Stockert, J. Lass +6
Although magnetic frustration in metals provides a promising avenue for novel quantum phenomena, their microscopic interpretation is often challenging. Here we use the face-centere…
Field-Induced Magnon Decay, Magnon Shadows, and Roton-like Excitations in the Honeycomb Antiferromagnet YbBr
J. A. Hernández, A. A. Eberharter, M. Schuler +9
Although the search for quantum many-body phenomena in magnetic materials has a strong focus on highly frustrated systems, even unfrustrated quantum magnets show a multitude of unc…
Symmetry Breaking on the Three-Dimensional Hyperkagome Lattice of Na_4Ir_3O_8
E. J. Bergholtz, A. M. Laeuchli, R. Moessner
We study the antiferromagnetic spin-1/2 Heisenberg model on the highly frustrated, three-dimensional, hyperkagome lattice of Na_4Ir_3O_8 using a series expansion method. We propose…
Emergent multipolar spin correlations in a fluctuating spiral - The frustrated ferromagnetic S=1/2 Heisenberg chain in a magnetic field
J. Sudan, A. Luscher, A. Laeuchli
We present the phase diagram of the frustrated ferromagnetic S=1/2 Heisenberg J_1-J_2 chain in a magnetic field, obtained by large scale exact diagonalizations and density matrix r…
Static impurities in the S=3/2 kagome lattice
A. Laeuchli, S. Dommange, B. Normand +1
We consider the effects of doping the S=3/2 kagome lattice with static, nonmagnetic impurities. By exact diagonalization calculations on small clusters we deduce the local spin cor…
