Background and Purpose

The aim of this workshop is to identify computational challenges in the investigation of both large and small quantum mechanical systems. Ultimately, quantum mechanics governs how the world around us evolves. Thus it is of tremendous importance to study how quantum effects at the microscopic level manifest themselves in macroscopic behavior. In the pursuit of this goal, two major research strands can be identified: (i) physicists and mathematicians typically study universal characteristics of suitably identified paradigmatic models, whereas (ii) chemists and material scientists concern themselves with the intricate nature of very specific molecular arrangements and molecules.

A related dichotomy is that between (a) small model systems and (b) the quantum statistical mechanics of large systems. The recent drive into nano-science has led to a situation in which the research strands (i) and (ii), and (a) and (b) are becoming increasingly coupled to produce a lively field of research, active on a broad range of interconnecting fronts. In addition, and as a partial consequence of the aforementioned drivers, computational methods are now very heavily used on length and time scales much beyond the originally envisaged scales. Consequently, the mathematical underpinning of these approaches and algorithms needs to be reconsidered and there is need for a cross-disciplinary effort to do so. To address these problems is the aim of our proposed workshop, which will be structured into 5 themes:

  1. Quantum Dynamics;
  2. Small Systems;
  3. Large Systems and Quantum Statistical Mechanics;
  4. Applications, including Quantum Chemistry and Materials;
  5. Underpinning Numerical Methods.
