We propose three distinct schemes for implementing local \textit{quantum friction} (QF) within the Hartree-Fock-Bogoliubov (HFB) approximation to efficiently dissipate energy in fermionic many-body systems. The first scheme introduces a local current-dependent potential in the Hamiltonian, the second incorporates an external pairing potential that conserves particle number, and the third...
Josephson junctions represent a powerful tool to probe macroscopic phase
coherence in different systems. They are also fundamental for atomtronics
circuits, thanks to their well defined current-chemical potential and current-phase. In our experimental system, we create atomic Josephson junctions using Fermi superfluids of lithium-6, realized by coupling two quasi-two-dimensional atomic...
