A mesoscopic superconductor with a magnetic moment in its center exhibits confined vortex loops with threefold symmetry in its center. Here, we show how the boundaries can affect this symmetry by considering a superconducting cube and sphere.

We report on flux confinement effects in superconducting submicron line, loop and dot structures. The main idea of our study was to vary the boundary conditions for confinement of the superconducting condensate by taking samples of different topology and, through that, modifying the lowest Landau le
The conductance fluctuations 6G of superconducting squares are examined. In the diffusive and strongly disordered regimes, 5G increases as the superconducting order parameter A is increased from zero, reaching a maximum when the superconducting coherence length is of order the localisation length of
The vortex dynamics in mesoscopic superconducting cylinders with rectangular cross section under an axially applied magnetic field is investigated in the multivortex London regime. The rectangles considered range from a square up to an infinite slab. The flux distribution and total flux carried by a
