Magnon interactions in a moderately correlated Mott insulator
Qisi Wang, S. Mustafi, E. Fogh +20
Quantum fluctuations in low-dimensional systems and near quantum phase transitions have significant influences on material properties. Yet, it is difficult to experimentally gauge…
Temperature dependence of the anomaly in the excitation spectrum of the 2D quantum Heisenberg antiferromagnet
W. Wan, N. B. Christensen, A. W. Sandvik +7
It is well established that in the low-temperature limit, the two-dimensional quantum Heisenberg antiferromagnet on a square lattice (2DQHAFSL) exhibits an anomaly in its spectrum…
Spin-Orbital Excitations in CaRuO Revealed by Resonant Inelastic X-ray Scattering
L. Das, F. Forte, R. Fittipaldi +19
The strongly correlated insulator CaRuO is considered as a paradigmatic realization of both spin-orbital physics and a band-Mott insulating phase, characterized by orbita…
Quantum dynamics and entanglement of spins on a square lattice
N. B. Christensen, H. M. Ronnow, D. F. McMorrow +6
Bulk magnetism in solids is fundamentally quantum mechanical in nature. Yet in many situations, including our everyday encounters with magnetic materials, quantum effects are maske…
