Transport of heat and hypersound with gigahertz (GHz) to terahertz (THz) phonons is crucial
for heat management in electronics, mediating signal processing with microwave radiation …

Coherent wave states such as Bose–Einstein condensates (BECs), which spontaneously
form in an overpopulated magnon gas even at room temperature, have considerable …

We study magnon hybridization in a ferrimagnetic heterostructure consisting of ultrathin
gadolinium iron garnet and yttrium iron garnet (YIG) layers and show the localized and …
