Thermal escape of fractional vortices in long Josephson junctions
U. Kienzle, T. Gaber, K. Buckenmaier +5
We consider a fractional Josephson vortex in a long 0-kappa Josephson junction. A uniformly applied bias current exerts a Lorentz force on the vortex. If the bias current exceeds t…
Escape Rate Measurements and Microwave Spectroscopy of 0, pi, and 0-pi ferromagnetic Josephson Tunnel Junctions
J. Pfeiffer, T. Gaber, D. Koelle +7
We present experimental studies of high quality underdamped 0, pi, and 0-pi ferromagnetic Josephson tunnel junctions of intermediate length L (lambda_J < L < 5 lambda_J, where lamb…
Theory of fractional vortex escape in a 0-kappa long Josephson junction
K. Vogel, T. Kato, W. P. Schleich +3
We consider a fractional Josephson vortex in an infinitely long 0-kappa Josephson junction. A uniform bias current applied to the junction exerts a Lorentz force acting on a vortex…
Semifluxon molecule under control
Andreas Dewes, Tobias Gaber, Dieter Koelle +2
Josephson junctions with a phase drop pi in the ground state allow to create vortices of supercurrent carrying only half of the magnetic flux quantum Phi_0~2.07*10^-15 Wb. Such sem…
Impact of the Meissner effect on magnetic micro traps for neutral atoms near superconducting thin films
D. Cano, B. Kasch, H. Hattermann +4
We theoretically evaluate changes in the magnetic potential arising from the magnetic field near superconducting thin films. An example of an atom chip based on a three-wire config…
Hot spots and waves in Bi2Sr2CaCu2O8 intrinsic Josephson junction stacks -a study by Low Temperature Scanning Laser Microscopy
H. B. Wang, S. Guénon, J. Yuan +6
Recently, it has been shown that large stacks of intrinsic Josephson junctions in Bi2Sr2CaCu2O8 emit synchronous THz radiation, the synchronization presumably triggered by a cavity…
