1305.4829 (Redouane Zamoum et al.)

Exact calculation of current correlations and admittance in the
fractional quantum Hall regime
   [PDF]

Redouane Zamoum, Adeline Crépieux
In this work, we focus on the finite frequency current-current correlations between edge states in a fractional quantum Hall two dimensional gas and on their relations to the quantum admittance. Using a refermionization method, we calculate these quantities within the same framework. Our results apply whatever the values of backscattering amplitude, frequency, voltage and temperature, allowing us to reach different regimes. Auto-correlations and cross-correlations exhibit distinct frequency dependencies that we discuss in detail.
