Theory of coherent quantum phase-slips in Josephson junction chains with periodic spatial modulations
Aleksandr E. Svetogorov, Masahiko Taguchi, Yasuhiro Tokura +2
We study coherent quantum phase-slips which lift the ground state degeneracy in a Josephson junction ring, pierced by a magnetic flux of the magnitude equal to half of a flux quant…
Mode engineering with a one-dimensional superconducting metamaterial
Masahiko Taguchi, Denis M. Basko, Frank W. J. Hekking
We propose a way to control the Josephson energy of a single Josephson junction embedded in one- dimensional superconducting metamaterial: an inhomogeneous superconducting loop, ma…
Quantum adiabatic pumping by modulating tunnel phase in quantum dots
Masahiko Taguchi, Satoshi Nakajima, Toshihiro Kubo +1
In a mesoscopic system, under zero bias voltage, a finite charge is transferred by quantum adiabatic pumping by adiabatically and periodically changing two or more control paramete…
