Flat band transport and Josephson effect through a finite-size sawtooth lattice
Ville A. J. Pyykkönen, Sebastiano Peotta, Philipp Fabritius +3
We study theoretically the transport through a finite-size sawtooth lattice coupled to two fermionic reservoirs kept in the superfluid state. We focus on the DC Josephson effect an…

Quantized conductance through a dissipative atomic point contact
Laura Corman, Philipp Fabritius, Samuel Häusler +5
Signatures of quantum transport are expected to quickly vanish as dissipation is introduced in a system. This dissipation can take several forms, including that of particle loss, w…

Quantized conductance through a spin-selective atomic point contact
Martin Lebrat, Samuel Häusler, Philipp Fabritius +3
We implement a microscopic spin filter for cold fermionic atoms in a quantum point contact (QPC) and create fully spin-polarized currents while retaining conductance quantization.…
