Accuracy and Precision for Extended Systems (APES) Group

Group Banner

We use and develop methods based on quantum theory to understand the physics and chemistry of molecules and solids. And we like their combination -- molecular solids -- the most, as they are very useful for understanding accuracy of methods as well very important in nature and industries.

Paper on alkali metal trimers in J. Chem. Phys.

May 8, 2025

Together with a colleague Dr. Soldan, we published a short study of binding curves of alkali metal trimers. It's our first use of the MRCC code which we used to calculate CCSDT(Q) energies.
