简介: |
A novel ultra-cold plasma produced in the expansion region of a supersonic
jet shows very intriguing properties that can be explained by electron
degeneracy and possible formation of an electron Wigner crystal. The
consequences of electron degeneracy on the crystallisation of the ions in
the plasma is discussed. The experimental observation of plasma compression
show that the plasma does not behave as a gas but it has condensed phase
properties, in line with theoretical predictions. This novel plasma could
open the perspective of obtaining a Bose-Einstein condensate of molecular
cations. |
