Charged complexes at the surface of liquid helium
arXiv:cond-mat/0210520 · doi:10.1002/pssb.200301800
Abstract
Charged clusters in liquid helium in an external electric field form a two-dimensional system below the helium surface. This 2D system undergoes a phase transition from a liquid to a Wigner crystal at rather high temperatures. Contrary to the electron Wigner crystal, the Wigner lattice of charged clusters can be detected directly.
