Are you active in, or interested in, the computational modelling/simulation of materials? Are you aware of what can (and cannot) be currently achieved using quantum mechanical or atomistic simulations? With the development of new algorithms, the ever growing rise in available computer power, and the availability of general purpose modelling codes, the answers might be different to what you think! In this 1-day meeting on Friday 6th Jan 2017, you will meet with leading researchers working with quantum / atomistic simulations from across the UK.

This free event will consist of invited and contributed talks, and a poster session. This event will be relevant for beginners and experts alike.

Confirmed Invited Speakers:

Prof. Rex Godby (University of York) – Many-electron Quantum Simulation of Matter

The theory of the electronic properties of condensed matter is a major challenge in many-particle quantum mechanics. The exact solution of the Schrödinger equation for more than a few interacting electrons is impossible. Nevertheless, powerful approximation techniques, based on underlying theoretical insights that are themselves exact, yield theories with remarkable predictive abilities in many cases. I will focus on two of the major theories, density-functional theory and many-body perturbation theory, and will relate them to experiments (including structural properties of matter, atom dynamics, and electron spectroscopies of various types).

Dr David Quigley (University of Warwick) – Exploring the Kinetics of Crystal Nucleation via Computer Simulation

The growth of crystals is a necessary step in manufacture of most pharmaceuticals and functional materials, but highly undesirable in other circumstances such as ice-fouling or the formation of kidney stones. Controlling or inhibiting these processes requires detailed molecular-level understanding of the initial nucleation process. Simulations are increasingly able to access information about this process through a combination of computational power and advanced sampling schemes. In this talk I will discuss ice and sodium chloride nucleation as prototypical problems, as well as simulations of idealised lattice models. In each case, results continue to challenge the accuracy of molecular models and the assumptions of classical nucleation theory.

Dr Marco Molinari (University of Huddersfield) – Modelling Transport Properties of Thermoelectric Materials

Thermoelectric devices convert heat into electricity and provide an efficient supplemental source of energy.  Oxides are promising thermoelectric materials stable at high temperatures and oxidising conditions. Oxides can be doped with a wide range of elements resulting in n-type and p-type materials, and more importantly can be synthesized with clean and sustainable elements compared to conventional thermoelectrics. The figure of merit (ZT=TσS2 /(κel)) is the measure of materials’ thermoelectric efficiency. ZT becomes optimal with high Seebeck coefficient, high electrical conductivity and low thermal conductivity. We will discuss the methods,
namely nanostructuring and band engineering, used to achieve enhanced properties.
