Problem 11.8.
Let us consider a Fermi gas with spin 1/2 and mass
m confined in the two dimen-
sional domain sketched in Fig. 11.3: in the (x, y)
plane, it is a triangle with base 2R
and height R. This gas is at temperature T = 0 and
is under the effect of a constant
gravitational field g. Compute the average number
N of fermions under the as-
sumption that the maximum height reached by the
gas is exactly the height of the
triangle.
