Just arxived our latest work! We introduce multimap targeted free energy estimation and use it to converge free energy corrections from a FF to a DFTB potential with a few thousand single-point QM calculations. No sampling from QM needed. 1/n

We present a new method to compute free energies at a quantum mechanical (QM) level of theory from molecular simulations using cheap reference potential energy functions, such as force fields. To...

The main idea is to train the CV from data generated with metadynamics of paths, which can enhance the sampling of (unbiased!) transition paths. 2/n.

We present a method to sample reactive pathways via biased molecular dynamics simulations in trajectory space. We show that the use of enhanced sampling techniques enables unconstrained exploration...

The method is orders of magnitude faster than standard FEP and seems to compare favorably also to nonequilibrium calculations (about 8x faster) on the same set of molecules. 3/n

Multimap estimators (we provide an extension of FEP and MBAR) compute the free energy using multiple normalizing flow neural networks. We exploit this to remove the need for a separate training phase and estimate the free energy during training. 2/n.
