Thermal escape of fractional vortices in long Josephson junctions (2009)
Kienzle, U., Gaber, T., Buckenmaier, K., Ilin, K., Siegel, M., Koelle, D., ...
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 the critical...
Pfeiffer, J., Gaber, T., Koelle, D., Kleiner, R., Goldobin, E., Weides, M., ...
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 lambda_J is the...
Observation of negative absolute resistance in a Josephson junction (2008)
Nagel, J., Speer, D., Gaber, T., Sterck, A., Eichhorn, R., Reimann, P., ...
We experimentally demonstrate the occurrence of negative absolute resistance (NAR) up to about $-1\Omega$ in response to an externally applied dc current for a shunted Nb-Al/AlO$_x$-Nb Josephson...
Spectroscopy of the fractional vortex eigenfrequency in a long Josephson 0-kappa junction (2006)
Buckenmaier, K., Gaber, T., Siegel, M., Koelle, D., Kleiner, R., Goldobin, E.
Fractional Josephson vortices carry a magnetic flux Phi, which is a fraction of the magnetic flux quantum Phi_0 ~ 2.07x10^{-15} Wb. Their properties are very different from the properties of the...

Non-ideal artificial phase discontinuity in long Josephson 0-kappa-junctions (2004)
Gaber, T., Goldobin, E., Sterck, A., Kleiner, R., Koelle, D., Siegel, M., ...
We investigate the creation of an arbitrary $\kappa$-discontinuity of the Josephson phase in a long Nb-AlO_x-Nb Josephson junction (LJJ) using a pair of tiny current injectors, and study the...

Dynamics of semifluxons in Nb long Josephson 0-pi junctions (2003)
Goldobin, E., Sterck, A., Gaber, T., Koelle, D., Kleiner, R.
We propose, implement and test experimentally long Josephson 0-pi junctions fabricated using conventional Nb-AlOx-Nb technology. We show that using a pair of current injectors, one can create an...
Polarization squeezing of intense pulses with a fiber Sagnac interferometer (2003)
Heersink, J., Gaber, T., Lorenz, S., Glöckl, O., Korolkova, N., Leuchs, G.
We report on the generation of polarization squeezing of intense, short light pulses using an asymmetric fiber Sagnac interferometer. The Kerr nonlinearity of the fiber is exploited to produce...
