Coherent spin pumping in a strongly coupled magnon-magnon hybrid system
Yi Li, Wei Cao, Vivek P. Amin +10
We experimentally identify coherent spin pumping in the magnon-magnon hybrid modes of permalloy/yttrium iron garnet (Py/YIG) bilayers. Using broadband ferromagnetic resonance, an "…

Vortices in a Monopole Superconducting Weyl Semi-metal
Canon Sun, Shu-Ping Lee, Yi Li
A monopole harmonic superconductor is a novel topological phase of matter with topologically protected gap nodes that result from the non-trivial Berry phase structure of Cooper pa…
