Order parameter fluctuations and collective modes in superconductors
- Univ. of Minnesota, Minneapolis, MN (United States)
Measurements of the frequency and wave vector dependence of the pair field susceptibility and the dynamical structure factor of homogeneous, short mean free path aluminum films have been carried out. These measurements critically probe the dynamical nature of order parameter fluctuations in the vicinity of the superconducting phase transition.
