Strong coupling between quantized magnon modes in a YIG microstucture and microwaves in a superconducting resonator
Seth W. Kurfman, Philipp Geyer, Anoop Kamalasanan +6
Strong-coupling experiments based on magnons enable the exploration into on-chip demonstrations involving numerous long-lived excitations. Yttrium iron garnet (YIG) has been consid…
Imaging Harmonic Generation of Magnons
Anthony J. D'Addario, Kwangyul Hu, Maciej W. Olszewski +4
This work combines theory and experiment to examine the mechanisms underlying the harmonic generation of magnons. We develop a nonlinear spin-wave framework that is directly analog…
Competing Lattice and Defect Dynamics Govern Terahertz-Induced Ferroelectricity in Quantum Paraelectric SrTiO
L. Cheng, K. Hu, S. Yang +3
Intense terahertz (THz) pulses induce transient inversion-symmetry breaking in quantum paraelectric SrTiO, yet the underlying mechanism remains controversial. Using fields up t…
Robust Edge States from Band Topology in a Damped One-dimensional Magnonic Crystal
Kwangyul Hu, Denis R. Candido, Michael E. Flatté
The presence or absence of topologically-produced edge states of a crystal are robust to disorder; their stability in the presence of decay is less clear. For topologically nontriv…
