“…the Bardeen-Cooper-Schrieffer (BCS) theory, are among the most important achievements in physics. The BCS paradigm successfully explains a large variety of phenomena ranging from the organization of nuclear matter [4,5] to the superconductivity in metals [6] and conjectures exist about the possibility that the final quantum state of a black hole would be similar to the ground state of a BCS superconductor [7,8].…”

We study inhomogeneous Cooper pairs distribution and localization effects in tree-like networks of superconducting islands coupled via Josephson weak links. Using a generalized Feynman’s approach, reminiscent of the Bose–Hubbard model, we demonstrate that the Cooper pairs fraction which localizes on a specific network’s island is limited by the network topology and, if present, by the repulsive interaction. These findings contribute to clarify the interplay between confinement effects induced by the network’s topology and interaction and shed some light on recent experiments dealing with networks of Josephson junctions.

“…Recently, it was pointed out that the Andreev reflection can be regarded as an analogue of Hawking radiation at a black hole event horizon [14][15][16] . By assuming a momentum-conserved tunneling, the Andreev reflection can provide an information-mirroring process which is similar to the black hole evaporation as Hayden and Preskill's proposal 17,18 .…”

It is found that Andreev reflection provides a deterministic teleportation process at an ideal normal-superconductor interface, making it behave like an information mirror. However, it is challenging to control the Andreev reflection in a spatially-separated junction due to the mode mixing at the interface. We theoretically propose the laser-induced Andreev reflection between two-component Fermi superfluid and normal states without mode mixing via spatially-uniform Rabi couplings. By analyzing the tunneling current up to the fourth order, we find that the Andreev current exhibits unconventional non-Ohmic transport at zero temperature. The Andreev current gives the only contribution in the synthetic junction system at zero detunings regardless of the ratio of the chemical potential bias to the superfluid gap, which is in sharp contrast to that in conventional junctions. Our result may give a potential impact on theoretical and experimental study of quantum many-body phenomena, and also pave a way for understanding the black hole information paradox through the Andreev reflection as a quantum-information mirror.
