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…

QFT in the flat chart of de Sitter space
Yusuke Korai, Takahiro Tanaka
We study the correlators for interacting quantum field theory in the flat chart of de Sitter space at all orders in perturbation. The correlators are calculated in the in-in formal…
