Thus we can say that the lifetime of particles at the Fermi surface goes to infinity.
Materials with complex crystal structures can have quite intricate Fermi surfaces.
In principle all fermion energy level populations are bound by a Fermi surface although the term is not generally used outside of condensed-matter physics.
The area of the Fermi surface is expressed in teslas.
In crystalline materials, the wave vectors of conduction electrons are very close to the Fermi surface.
When the external magnetic field is increased in an isolated system, the Landau levels expand, and eventually "fall off" the Fermi surface.
Brian Pippard used it to determine the Fermi surface of copper.
It is also used as a method of measuring the Fermi surface and band structure in metals.
These result from multiple nesting wavevectors coupling different flat regions of the Fermi surface.
(These quantities are not well-defined in cases where the Fermi surface is non-spherical).
