Optimized Tensor-Network Renormalization for Quantum Dynamics: Resolving the Spectral Function of
Jiahang Hu, Runze Chi, B. Normand +2
Tensor-network methods have opened a powerful route for the study of dynamical spectral functions in two-dimensional quantum systems. However, existing approaches within the framew…
Dynamical Spectral Function of the Kagome Quantum Spin Liquid
Jiahang Hu, Runze Chi, Yibin Guo +3
Quantum spin liquids (QSLs) host exotic fractionalized magnetic and gauge-field excitations whose microscopic origins and experimental verification remain frustratingly elusive. In…
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…
Magnetic and phononic dynamics in the two-ladder quantum magnet (C5H9NH3)2CuBr4
J. Philippe, F. Elson, T. Arh +20
In quantum magnetic materials it is common to observe both static and dynamic lattice effects on the magnetic excitation spectrum. Less common is to find that the magnetic correlat…
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…
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…
