Theoretical Chemistry

Jacob Group

Computer simulations provide insights into molecular systems that would not be possible from experiment alone. We develop quantum-chemical methods for the description of complex chemical systems – ranging from biomolecules to materials. We apply these methods to study spectroscopic properties and to design functional chemical systems – for energy conversion, for catalysis, and for drug discovery.

In this paper, we present the Amsterdam Modeling Suite (AMS), a comprehensive software platform designed to support advanced molecular and materials simulations across a wide range of chemical and physical systems. AMS integrates cutting-edge quantum chemical methods, including Density Functional Theory (DFT) and time-dependent DFT, with molecular mechanics, fluid thermodynamics, machine learning techniques, and more, to enable multi-scale modeling of complex chemical systems. Its design philosophy allows for seamless coupling between components, facilitating simulations that range from small molecules to complex biomolecular and solid-state systems, making it a versatile tool for tackling interdisciplinary challenges, both in industry and in academia. The suite also emphasizes user accessibility, with an intuitive graphical interface, extensive scripting capabilities, and compatibility with high-performance computing environments.

Research

Our research aims at the theoretical description of complex chemical systems. Ultimately, we want to enable a quantum-chemical design of functional chemical systems.

Our group develops simulation methods for complex chemical systems that make it possible to treat large chemical systems with hundreds to thousands of atoms. To this end, we develop multiscale methods that enable an efficient treatment by using a partitioning into smaller subsystems and that make it possible to combine different quantum-chemical methods. In addition, we develop quantum-chemical methods for theoretical spectroscopy, work on next-generation density-functional theory approaches, and apply computational methods for challenging problems of modern chemistry.

Our method development is driven by concrete applications, on which we work in interdisciplinary collaborations with experimental groups. This ranges from the elucidation of catalytic reaction mechanism over drug discovery to computational materials design.

Subsystem Quantum Chemistry
By partitioning them into smaller building blocks, we make calculations for very large molecules possible.
Theoretical Spectroscopy
We develop novel computational tools for modelling modern spectroscopic experiments
Density-Functional Theory
We develop next-generation density-functional theory methods.
Software
We develop modern software for quantum chemistry.

Theses and Lab Courses

Bachelor and Master theses on topics of our research projects in theoretical chemistry are possible at any time. Student research projects as part of the PC-F advanced lab course (B.Sc. Chemistry) as well as research labs (M.Sc. Chemistry and M.Sc. Chemical Biology) can also be done in theoretical chemistry.

Topics for theses and lab courses


Innovation Project "Computational Chemistry Research Lab"

In our innovative project, the "Quantenchemie 2" module of the bachelor's program in chemistry is transformed into a "Computational Chemistry Research Lab".

Transfer Project "Tasthirn"

Successfull innovative teaching-learning projects can be transferred to other departments at the TU Braunschweig within the "Transferprogramm". We have transferred our teaching-learning concept "Chemie3D", which dealt with the visualization of complex three-dimensional contents, to neurobiology.

Chemie3D

As part of the "in medias res" funding program, we developed an innovative teaching concept for the use of a 3D printer and virtual reality (VR) glasses in lectures and computational chemistry labs.
