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…
Functionalized high-speed magnon-polaritons resulting from the magnetic antenna effect
Kenta Kato, Tomohiro Yokoyama, Hajime Ishihara
Magnon-polaritons (MPs) refer to a light--magnon coupled state and can potentially act as information carriers, possibly enabling charge-free computation. However, the light--magno…
Nonlocal inelastic scattering of light: Enhanced and noiseless signals in remote-coupled optomechanical systems
Sho Tamaki, Tomohiro Yokoyama, Hajime Ishihara
The inelastic scatterings of matter systems, such as Raman scattering, contain rich information on mechanical vibrations like as resonant frequencies, which lead to various applica…
Comprehensive Microscopic Theory for Coupling of Longitudinal--Transverse Fields and Individual--Collective Excitations
Tomohiro Yokoyama, Masayuki Iio, Takashi Kinoshita +2
A plasmon is a collective excitation of electrons due to the Coulomb interaction. Both plasmons and single-particle excitations (SPEs) are eigenstates of bulk metallic systems and…
