Theory of planar quasi-ballistic Josephson junctions
G. A. Bobkov, I. V. Bobkova, A. M. Bobkov +2
We develop a theoretical framework for planar quasi-ballistic Josephson junctions, where multiple superconducting leads are coupled through a large, nearly ballistic normal metal c…
Multiterminal Ballistic Josephson Effect in Monocrystalline Gold
K. B. Polevoy, G. A. Bobkov, D. S. Kalashnikov +6
We report on the realization of a planar, quasi-ballistic Josephson junction array using a Au micron-sized single-crystal. The system exhibits a nonlocal, multiterminal Josephson e…
Evidence for atomic-scale vibron-mediated electron bunching
A. Maiti, M. Amato, V. S. Stolyarov +5
Due to the Coulomb blockade effect, electrons rarely bunch during transport, a phenomenon observed only in a few specially engineered mesoscopic configurations. In this work, we in…
Competitive helical bands and highly efficient diode effect in F/S/TI/S/F hybrid structures
T. Karabassov, I. V. Bobkova, V. S. Stolyarov +2
The diode effect in superconducting materials has been actively investigated in recent years. Plenty of different devices have been proposed as a platform to observe the supercondu…
