Event details
In simulations it is often useful to compute how some quantity changes when we perturb the system. However it is time consuming to run multiple simulations for different values of the perturbation. In some cases this problem can be avoided using Einstein or Green-Kubo relations but this is not always possible. We have devised an algorithm for computing the response to perturbations in Brownian dynamics simulations which is generic: it works for any type of perturbation and does not assume equilibrium. I will explain what this algorithm is and show that it works for a simple example.
