" It expresses the balance between friction, which tends to drive
any system to a completely 'dead' state, and noise, which
tends to keep the system 'alive'. This balance is required
to have a thermal equilibrium state at long times. "
where noise = fluctuation
friction = dissipation
BTW, Is there anybody have good suggestions about how to
start if I want to do some numerical computation with stochastic method. |
