Welcome to the Atomistic Simulation Centre - ASC
Atomistic simulation is the theoretical and computational modelling of what happens
at the atomic scale in solids, liquids, molecules and plasmas. Often this means solving
numerically the classical or quantum-mechanical microscopic equations for the motion
of interacting atoms, or even deeper - electrons and nuclei.
Atomistic simulation is used: (1) to interpret existing experimental data and predict
new phenomena; (2) to reach computationally where pen-and-paper theory alone cannot;
(3) to provide a way forward where experiments are not yet possible, e.g. under extreme
conditions, or at atomistic size- and time-scales where one cannot yet look directly.
In the ASC we are especially interested in the real-time dynamics of classical and quantum
systems. We develop new methods, write computer packages and apply these modelling
techniques in the following flagship areas:
- Electronic transport in nanostructures
- Irradiation of materials and biological systems
- Ultra-fast laser-matter interactions
We also develop integrated approaches that exploit theoretical understanding to
rationally design processes and functional materials, which have the potential to
generate disruptive technologies.
