Computer Chemistry Center


The Computer Chemistry Center (CCC) was founded in 1993; it currently comprises four research groups who work on simulations of biological systems (Imhof, Clark), solid-state materials and surface chemistry (Meyer) and the design of materials and processes (Zahn, also Theoretical Chemistry). Prof. Petra Imhof will take over from Prof. Clark as Technical Director in March 2020.

Methods and Software

The research topics treated in CCC range from protein and DNA simulations and computational drug design to simulation and design of new materials. Together, the four groups in CCC use a spectrum of calculation techniques from Ab initio molecular-orbital theory, density-functional theory (DFT), semiempirical molecular-orbital theory (SEMO) to classical molecular dynamics, first-principles molecular dynamics, multi-timescale simulations and graph theory.

A wide range of software packages is used:

Members of CCC are  participating in software development for  CPMD, LAMMPS and Psi4. Further more EMPIRE an standalone in-house simulation suite is developed at CCC.
