Molecular Physics
Umbrella sampling is a computational technique used in molecular simulations to enhance the sampling of rare events by effectively creating a biasing potential that flattens the free energy landscape. This method allows researchers to gather more data about specific configurations that are otherwise difficult to access due to high energy barriers. By applying an external bias, it helps to improve convergence in simulations, especially when exploring complex free energy surfaces or reaction pathways.
congrats on reading the definition of umbrella sampling. now let's actually learn it.
