Abstract

Abstract: Spinconversion is a collective concept underlying spin mediated energy interconversion among electricity, light, sound, vibration, and heat. Particularly in the last couple of decades, the increasing research efforts result in enhancements of spinconversion efficiencies and the discovery of novel spinconversion mechanisms. Here, an overview of the progress in spinconversion is layed out. In particular, the involvement of band crossings at which quasiparticles are formed with consequences beyond that of efficient spinconverison are discussed. Abstract : The recent progress in spinconversion research is reviewed, with particular focus on studies involving band crossing. If the coupling strength of quasiparticles is enhanced, hybrid quasiparticles are formed and band anticrossings appear, with repercussions in other research fields beyond spinconversion, such as quantum information.
