Vortex Creation in Bose-Einstein Condensates by Laser Beam Vortex Guiding
Kestutis Staliunas
A technique for vortex creation in trapped Bose-Einstein condensates is suggested: Vortices can be excited at the edge of a condensate and guided to the center by a laser beam movi…
Coulomb blockade and cotunneling in single electron circuits with on-chip resistors: towards the implementation of R-pump
A. B. Zorin, S. V. Lotkhov, H. Zangerle +1
We report on the investigation of Al single electron structures equipped with miniature (8 um long) on-chip Cr resistors of R > R_k = h/e^2 = 25.8 kOhm. From the measurement of the…
Magnetic Field Dependent Tunneling in Glasses
P. Strehlow, M. Wohlfahrt, A. G. M. Janssen +4
We report on experiments giving evidence for quantum effects of electromagnetic flux in barium alumosilicate glass. In contrast to expectation, below 100 mK the dielectric response…
Non-Gaussian distribution of nearest-neighbour Coulomb peak spacings in metallic single electron transistors
M. Furlan, T. Heinzel, B. Jeanneret +2
The distribution of nearest-neighbour spacings of Coulomb blockade oscillation peaks in normal conducting aluminum single electron transistors is found to be non-Gaussian. A pronou…
Localization of electrons in two-dimensional spatially-correlated random magnetic fields
H. Potempa, L. Schweitzer
The localization properties of electrons moving in a plane perpendicular to a spatially-correlated static magnetic field of random amplitude and vanishing mean are investigated. We…
Frequency dependent conductivity in the integer quantum Hall effect
A. Bäker, L. Schweitzer
Frequency dependent electronic transport is investigated for a two-dimensional disordered system in the presence of a strong perpendicular static magnetic field. The ac-conductivit…
