 Overdamped Langevin dynamics

ID: overdamped-langevin-dynamics

For potential

F

and mobility

M

d X_{t} = - M \nabla F (X_{t}) d t + 2 k_{B} T M d W_{t} .

The matching noise amplitude is the fluctuation-dissipation relation that makes the Boltzmann density proportional to

e^{- F / (k_{B} T)}

invariant.
