Inversion in a four terminal superconducting device on the quartet line: II. Quantum dot and Floquet theory
Régis Mélin, Benoît Douçot
In this paper, we consider a quantum dot connected to four superconducting terminals biased at opposite voltages on the quartet line. The grounded superconductor contains a loop th…
Inversion in a four-terminal superconducting device on the quartet line: I. Two-dimensional metal and the quartet beam splitter
Régis Mélin
In connection with the recent Harvard group experiment on graphene-based four-terminal Josephson junctions containing a grounded loop, we consider biasing at opposite voltages on t…
Berry phase in superconducting multiterminal quantum dots
Benoit Doucot, Romain Danneau, Kang Yang +2
We report on the study of the non-trivial Berry phase in superconducting multiterminal quantum dots biased at commensurate voltages. Starting with the time-periodic Bogoliubov-de G…
Engineering the Floquet spectrum of superconducting multiterminal quantum dots
Régis Mélin, Romain Danneau, Kang Yang +2
Here we present a theoretical investigation of the Floquet spectrum in multiterminal quantum dot Josephson junctions biased with commensurate voltages. We first draw an analogy bet…
Simple Floquet-Wannier-Stark-Andreev viewpoint and emergence of low-energy scales in a voltage-biased three-terminal Josephson junction
Régis Mélin, Jean-Guy Caputo, Kang Yang +1
A three-terminal Josephson junction consists of three superconductors coupled coherently to a small nonsuperconducting island, such as a diffusive metal, a single or double quantum…
Non-local Supercurrent of Quartets in a Three-Terminal Josephson Junction
Yonatan Cohen, Yuval Ronen, Jung-Hyun Kang +4
We report an observation of a new, non dissipative and non local supercurrent, carried by quartets; each consisting of four entangled electrons. The supercurrent is a result of a n…
