The effect of Magnetic Field on MQT Escape Time in "Small" Josephson Junctions
Yu. N. Ovchinnikov, A. Barone, A. A. Varlamov
We study the phenomenon of macroscopic quantum tunneling (MQT) in a finite size Josephson junction (JJ) with an externally applied magnetic field. As it is well known, the problem…

Evidence for High Tc Superconducting Transitions in Isolated Al45- and Al47- Nanoclusters
Baopeng Cao, Colleen M. Neal, Anne K. Starace +3
Heat capacities measured for Al45- and Al47- nanoclusters have reproducible jumps at ~ 200 K. These jumps are consistent with theoretical predictions that some clusters with highly…
