Mesoscopic transport of fermions through an engineered optical lattice connecting two reservoirs
Martin Bruderer and Wolfgang Belzig
Phys. Rev. A 85, 013623 (2012)
In this recent article the flow of a Fermi gas between two reservoirs connected by a short optical lattice is examined. We show how the flow of the fermions can be controlled by modulating the optical lattice and derive the equations that govern the full equilibration between the reservoirs. In contrast to classical fluids, the particle current exhibits measurable quantum fluctuations caused by the probabilistic nature of the transmission through the optical lattice. Moreover, even weak interactions between fermions have a strong blocking effect on the current. The described setup is a versatile testbed for studying non-equilibrium quantum many-body effects owing to the slow dynamics of the equilibration process and the possibility to detect fermions in small numbers.
Recent news:
Start of the second funding period of SFB 767
