In this topical group, we discuss advanced / meta sampling techniques. We concentrate on two main problems, namely the sampling of rare transitions and free energies.


The meeting takes place biweekly on Tuesdays at 10:30, if not indicated differently.

For rare events, we use

  • Forward Flux Sampling
  • Transition Interface Sampling

The standard tool here is FRESHS

For free energy calculations

  • Umbrella Sampling
  • Metadynamics

The standard tool here is PLUMED
