Pulsed Magnetophononics in Gapped Quantum Magnets
B. Demazure, M. Krebs, G. S. Uhrig +1
One route to the control of quantum magnetism at ultrafast timescales is magnetophononics, the modulation of magnetic interactions by coherently driven lattice excitations. Theoret…

Confined and deconfined spinon excitations in the rectangular-lattice quantum antiferromagnet
N. E. Shaik, E. Fogh, B. Dalla Piazza +3
Fractionalization remains one of the most fascinating manifestations of strong interactions in quantum many-body systems. In quantum magnetism, the existence of spinons -- collecti…

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…
