Probing Pauli Blocking Factors in Quantum Pumps with Broken Time-Reversal Symmetry
arXiv:cond-mat/0006331 · doi:10.1103/PhysRevLett.85.174
Abstract
A recently demonstrated quantum electron pump is discussed within the framework of photon-assisted tunneling. Due to lack of time-reversal symmetry, different results are obtained for the pump current depending on whether or not final-state Pauli blocking factors are used when describing the tunneling process. Whilst in both cases the current depends quadratically on the driving amplitude for moderate pumping, a marked difference is predicted for the temperature dependence. With blocking factors the pump current decreases roughly linearly with temperature until k_B T ~ \hbarωis reached, whereas without them it is unaffected by temperature, indicating that the entire Fermi sea participates in the electronic transport.
