Peak effect at the weak- to strong pinning crossover
J. A. G. Koopmann, V. B. Geshkenbein, G. Blatter
In type-II superconductors, the magnetic field enters in the form of vortices; their flow under application of a current introduces dissipation and thus destroys the defining prope…

Weak- to strong pinning crossover
G. Blatter, V. B. Geshkenbein, J. A. G. Koopmann
Material defects in hard type II superconductors pin the flux lines and thus establish the dissipation-free current transport in the presence of a finite magnetic field. Depending…

Impact of long-range interactions on the disordered vortex lattice
J. A. G. Koopmann, V. B. Geshkenbein, G. Blatter
The interaction between the vortex lines in a type-II superconductor is mediated by currents. In the absence of transverse screening this interaction is long-ranged, stiffening up…
