Josephson diode effect derived from short-range coherent coupling
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +6
Superconducting devices with broken time-reversal and spatial-inversion symmetries can exhibit novel superconducting phenomena. The observation of superconducting diode effects, wh…
Engineering of anomalous Josephson effect in coherently coupled Josephson junctions
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +6
A Josephson junction (JJ) is a key device in the development of superconducting circuits, wherein a supercurrent in the JJ is controlled by the phase difference between the two sup…
Phase-dependent Andreev molecules and superconducting gap closing in coherently coupled Josephson junctions
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +8
The Josephson junction (JJ) is an essential element of superconducting (SC) devices for both fundamental and applied physics. The short-range coherent coupling of two adjacent JJs…
Phonon-mediated spin dynamics in a two-electron double quantum dot under a phonon temperature gradient
Kazuyuki Kuroyama, Sadashige Matsuo, Seigo Tarucha +1
We have theoretically studied phonon-mediated spin-flip processes of electrons in a GaAs double quantum dot (DQD) holding two spins, under a phonon temperature gradient over the DQ…
