Two-dimensional macroscopic quantum tunneling in multi-gap superconductor Josephson junctions
Hidehiro Asai, Shiro Kawabata, Yukihiro Ota +1
Low-temperature characters of superconducting devices yield definite probes for different superconducting phenomena. We study the macroscopic quantum tunneling (MQT) in a Josephson…

Theory of macroscopic quantum tunneling with Josephson-Leggett collective excitations in multi-band superconducting Josephson junctions
Hidehiro Asai, Yukihiro Ota, Shiro Kawabata +2
Collective excitations reveal fundamental properties and potential applications of superconducting states. We theoretically study macroscopic quantum tunneling (MQT) in a Josephson…
