Bose-Einstein condensation of magnons in spin pumping systems
Kouki Nakata, Yusuke Korai
We clarify the condition for the occurrence of magnon Bose-Einstein condensation (BEC) in spin pumping systems without using external pumping magnetic fields. The Goldstone model i…

The temperature dependence of quantum spin pumping generated using electron spin resonance with three-magnon splittings
Kouki Nakata
On the basis of the Schwinger-Keldysh formalism, we have closely investigated the temperature dependence of quantum spin pumping by electron spin resonance. We have clarified that…
