Resonances and antiresonances in heat generation by spin current in a quantum dot

Abstract

We study the heat generation in a quantum dot exposed to a rotating magnetic field and coupled to
 a normal lead. Both electron-phonon interaction and electron-electron interaction are considered in the dot.
We show the emergence of resonances and antiresonances in the heat generation, which we attribute to 
constructive interference and destructive interference between phonon waves emitted from opposite
 spin channels in the dot.
