  Title Excess of topological defects induced by confinement in vortex nanocrystals Type Journal Article
  Year 2017 Publication Physical Review B Abbreviated Journal PRB  
  Volume 96 Issue 2 Pages 024507  
  Abstract We directly image individual vortex positions in nanocrystals in order to unveil the structural property that contributes to the depletion of the entropy jump entailed at the first-order transition. On reducing the nanocrystal size, the density of topological defects increases near the edges over a characteristic length. Within this “healing-length” distance from the sample edge, vortex rows tend to bend, while towards the center of the sample, the positional order of the vortex structure is what is expected for the Bragg-glass phase. This suggests that the healing length may be a key quantity to model confinement effects in the first-order transition of extremely layered vortex nanocrystals.
