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.

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

Group members:

     Kai Kratzer (KK) (group leader)

     Evangelos Ribeiro Tzaras (ET)
     Julian Michalowsky (JM)
     Jonas Landsgesell (JL)
     Johannes Zeman (JZ)
