Localizing quantum phase slips in one-dimensional Josephson junction chains
Ergül, Adem; Lidmar, Jack; Johansson, Jan; Azizoǧlu, Yaǧiz; Schaeffer, David; Haviland, David B. (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
Ergül, Adem; Schaeffer, David; Lindblom, Magnus; Haviland, David B.; Lidmar, Jack; Johansson, Jan (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 ...
