A Szemerédi-Trotter Theorem in Arbitrary Fields
Mark Lewko
Let be a field of characteristic . We prove that points and lines in determine at most incidences, the last term being omitted in c…
Saturation of thermal and spin conductances in a dissipative superfluid junction
Meng-Zi Huang, Philipp Fabritius, Jeffrey Mohan +3
Fermionic superfluid junctions typically exhibit suppressed thermal and spin transport due to the presence of a pairing gap but allow coherent particle transport. While dissipation…
Dark state transport between unitary Fermi superfluids
Mohsen Talebi, Simon Wili, Jeffrey Mohan +3
The formation of dark states is an important concept in quantum sciences, but its compatibility with strong interparticle interactions -- for example, in a quantum degenerate gas -…
Universal entropy transport far from equilibrium across the BCS-BEC crossover
Jeffrey Mohan, Philipp Fabritius, Mohsen Talebi +3
The transport properties of strongly interacting fermionic systems can reveal exotic states of matter, but experiments and theory have predominantly focused on bulk systems in the…
Irreversible entropy transport enhanced by fermionic superfluidity
Philipp Fabritius, Jeffrey Mohan, Mohsen Talebi +4
The nature of particle and entropy flow between two superfluids is often understood in terms of reversible flow carried by an entropy-free, macroscopic wavefunction. While this wav…
DC transport in a dissipative superconducting quantum point contact
Anne-Maria Visuri, Jeffrey Mohan, Shun Uchino +3
We study the current-voltage characteristics of a superconducting junction with particle losses at the contacts. We adopt the Keldysh formalism to compute the steady-state current…
Superfluid signatures in a dissipative quantum point contact
Meng-Zi Huang, Jeffrey Mohan, Anne-Maria Visuri +6
We measure superfluid transport of strongly interacting fermionic lithium atoms through a quantum point contact with local, spin-dependent particle loss. We observe that the charac…
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…
Interaction-Assisted Reversal of Thermopower with Ultracold Atoms
Samuel Häusler, Philipp Fabritius, Jeffrey Mohan +3
We study thermoelectric currents of neutral, fermionic atoms flowing through a mesoscopic channel connecting a hot and a cold reservoir across the superfluid transition. The thermo…
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…
