Langevin equation: ballistic and diffusive regime; Einstein relation
as a first basic example of fluctuation-dissipation relation. Langevin
equation in the presence of a conservative force (section
1.4.1)
Fokker-Planck approach: transition rates
and master equation for the probability density (gain term and loss
term) (section 1.4.2)
[be careful: I changed the
notation with respect to the one used in the book: I used R(x,x') in
place of W(x,x') to be consistent with the notation used in section 1.6]
