| Abstract | We experimentally study the dynamical response of the superconducting vortex system near the solid-liquid transition by applying forces parallel and perpendicular to a planar random defect array. Our results show that for magnetic fields above a certain critical field Hcr'? 4 T the solid glassy vortex phase in YBa2Cu3O7-? crystals with oriented twin planes does not correspond to the so-called Bose-glass phase. | ||||

| Title | Geometrical Confinement Effects in Layered Mesoscopic Vortex Matter | Type | Journal Article | ||
| Year | 2015 | Publication |
Journal of Low Temperature Physics | Abbreviated Journal | J. Low Temp. Phys. |
| Volume | 179 | Issue | 1-2 | Pages | 35-41 |
| Keywords | Vortex matter; Mesoscopic physics; Layered superconductors | ||||
| Abstract | We study the geometrical confinement effect in Bi 2 Sr 2 CaCu 2 O 8+δ mesoscopic vortex matter with edge-to-surface ratio of 7–12 %. Samples have in-plane square and circular edges, 30 μ m widths, and ∼ 2 μ m thickness. Direct vortex imaging reveals the compact planes of the structure align with the sample edge by introducing topological defects. The defect density is larger for circular than for square edges. Molecular dynamics simulations suggest that this density is not an out-of-equilibrium property but rather determined by the geometrical confinement. | ||||
