Band and Correlated Insulators of Cold Fermions in a Mesoscopic Lattice
Band and Correlated Insulators of Cold Fermions in a Mesoscopic Lattice
We investigate the transport properties of neutral, fermionic atoms passing through a one-dimensional quantum wire containing a mesoscopic lattice. The lattice is realized by projecting individually controlled, thin optical barriers on top of a ballistic conductor. Building an increasingly longer lattice, one site after another, we observe and characterize the …
