Localizing quantum phase slips in one-dimensional Josephson junction chains
(Journal article; Peer reviewed, 2013)We studied quantum phase-slip (QPS) phenomena in long one-dimensional Josephson junction series arrays with tunable Josephson coupling. These chains were fabricated with as many as 2888 junctions, where one sample had a ... -
Phase sticking in one-dimensional Josephson junction chains
(Journal article; Peer reviewed, 2013)We studied current-voltage characteristics of long one-dimensional Josephson junction chains with Josephson energy much larger than charging energy, EJ EC. In this regime, typical I-V curves of the samples consist of a ... -
Spin transport in ferromagnetic/normal-metal tunnel junction arrays
(Journal article; Peer reviewed, 2012)An array of alternating ferromagnetic and normal-metal islands separated by small tunnel junctions is theoretically investigated in the sequential tunneling regime. A numerical Monte Carlo method is used to calculate the ...
