" Fermi distribution of Fermi-surf "

 

Abstract

When a classical device suddenly perturbs a degenerate Fermi gas a coherent Fermi state arises. Coherent Fermi states involve an infinite superposition of particles and holes arranged in such a manner that there are no holes in the Fermi sea but the Fermi level depends on time and space - a Fermi-surf.

Fermi distribution and other features  of a Fermi-surf has a universal nature.  It is described by Airy functions regardless of details of a perturbation.
