The emergence of atomic semifluxons in optical Josephson junctions

M. Grupp, W. P. Schleich, E. Goldobin +3

We propose to create pairs of semifluxons starting from a flat-phase state in long, optical 0-pi-0 Josephson junctions formed with internal electronic states of atomic Bose-Einstei…

Sub-μm Josephson Junctions for Superconducting Quantum Devices

J. M. Meckbach, M. Merker, S. J. Buehler +7

For high-performance superconducting quantum devices based on Josephson junctions (JJs) decreasing lateral sizes is of great importance. Fabrication of sub-μm JJs is challenging du…

Josephson junction with magnetic-field tunable current-phase relation

A. Lipman, R. G. Mints, R. Kleiner +2

We consider a 0- Josephson junction consisting of asymmetric 0 and regions of different lengths and having different critical current densities and $j_…

A tunable macroscopic quantum system based on two fractional vortices

D. M. Heim, K. Vogel, W. P. Schleich +3

We propose a tunable macroscopic quantum system based on two fractional vortices. Our analysis shows that two coupled fractional vortices pinned at two artificially created κ disco…

Magnetic field dependence of the critical current in YBa_2Cu_3O_{7-δ}/Au/Nb ramp-zigzag Josephson junctions

S. Scharinger, M. Turad, A. Stoehr +5

We study the critical current I_c dependence on applied magnetic field H for multifacet YBa_2Cu_3O_{7-δ}-Au-Nb ramp-type zigzag Josephson junctions. For many experiments one would…

Experimental evidence of a ϕ Josephson junction

H. Sickinger, A. Lipman, M. Weides +5

We demonstrate experimentally the existence of Josephson junctions having a doubly degenerate ground state with an average Josephson phase ψ=\pmϕ. The value of ϕ can be chosen by d…
