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…
Competing Fractional Quantum Hall and Electron Solid Phases in Graphene
Shaowen Chen, Rebeca Ribeiro-Palau, Kang Yang +5
We report experimental observation of the reentrant integer quantum Hall effect in graphene, appearing in the N2 Landau level. Similar to high-mobility GaAs/AlGaAs heterostructu…
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…
