Vortex fluctuations in YBCO thin films: influence of weak magnetic fields
Flux-noise and ac susceptibility measurements have been performed on epitaxial YBa2Cu3O7 films. The validity of the fluctuation-dissipation-theorem is verified by the proportionality between flux…
Flux noise in MgB2 films
We have performed flux noise and AC-susceptibility measurements on two 400 nm thick MgB2 films. Both measurement techniques give information about the vortex dynamics in the sample, and hence the…

Extremely High Frequency Dependence of Two-Dimensional Superfluid Onset(Condensed matter: structure and mechanical and thermal properties)
We observed the frequency dependence of the superfluid transition of 4 He films adsorbed on planar gold up to a very high frequency of 180 MHz, using the overtone harmonic modes of a quartz crystal…

TLDR
The origins and the early work on transitions driven by topological defects such as vortices in the two dimensional planar rotor model and in (4)Helium films and dislocations and disclinations in 2D crystals are reviewed.
