Method to determine defect positions below a metal surface by STM
Ye. S. Avotina, Yu. A. Kolesnichenko, A. N. Omelyanchouk +2
The oscillatory voltage dependence of the conductance of a quantum point contact in the presence of a single point-like defect has been analyzed theoretically. Such signals are det…
DC SQUID based on the mesoscopic multiterminal Josephson junction
M. H. S. Amin, A. N. Omelyanchouk, A. M. Zagoskin
A theory is offered for a novel device, mesoscopic four-terminal SQUID. The studied system consists of a mesoscopic four-terminal junction, one pair of terminals of which is incorp…
Multi-Terminal Superconducting Phase Qubit
M. H. S. Amin, A. N. Omelyanchouk, A. Blais +4
Mesoscopic multi-terminal Josephson junctions are novel devices that provide weak coupling between several bulk superconductors through a common normal layer. Because of the nonloc…
The influence of single magnetic impurities on the conductance of quantum microconstrictions
A. Namiranian, Yu. A. Kolesnichenko, A. N. Omelyanchouk
The nonlinear ballistic conductance of three-dimensional quantum microconstrictions, which contain magnetic impurities, is investigated. The nonlinear part of the conductance, whic…
Effect of quantum interference in the nonlinear conductance of microconstrictions
A. Namiranian, Yu. A. Kolesnichenko, A. N. Omelyanchouk
The influence of the interference of electron waves, which were scattered by single impurities, on nonlinear quantum conductance of metallic microconstrictions (as was recently inv…
Coherent current states in mesoscopic four-terminal Josephson junction
Malek Zareyan, A. N. Omelyanchouk
A theory is offered for the ballistic 4-terminal Josephson junction. The studied system consists of a mesoscopic two-dimensional normal rectangular layer which is attached in each…
