Noise at a Fermi-edge singularity
arXiv:cond-mat/0609738 · doi:10.1103/PhysRevB.75.233304
Abstract
We present noise measurements of self-assembled InAs quantum dots at high magnetic fields. In comparison to I-V characteristics at zero magnetic field we notice a strong current overshoot which is due to a Fermi-edge singularity. We observe an enhanced suppression in the shot noise power simultaneous to the current overshoot which is attributed to the electron-electron interaction in the Fermi-edge singularity.
