Double quantum dot scenario for spin resonance in current noise

Research output: Contribution to journalArticlepeer-review

5 Scopus citations


We show that interference between parallel currents through two quantum dots, in the presence of spin-orbit interactions and strong on-site Coulomb repulsion, leads to resonances in current noise at the corresponding Larmor frequencies. An additional resonance at the difference of Larmor frequencies is present even without spin-orbit interaction. The resonance lines have strength comparable to the background shot noise and therefore can account for the numerous observations of spin resonance in scanning tunneling microscope noise with nonpolarized leads. We solve also several other models that show similar resonances.
