WCPM hosts regular seminars where we invite speakers working both in fundamental methodology and on applications of predictive modelling and UQ.

From October 2016, the seminars are on Mondays, 1pm and joint with the Centre for Scientific Computing, with a focus on all aspects of research involving significant computational resource. Venues are alternating between PS0.17a (Physical Sciences) and D2.02 (Engineering), and a sandwich lunch is available from 12:45pm.

If you would like to be kept informed of upcoming seminars, please do sign up here or send an email to wcpm-seminar-join at listserv dot csv dot warwick dot ac dot uk.

Past presentations are available below.

Tribology of diamond and silicon: atomic-scale insights from computers simulations

Tribological processes involving diamond and silicon are very common in technology. Chemical-mechanical polishing of diamond films and their ultralow friction in presence of water, wear of diamond-coated cutting tools, multi-wire sawing of silicon for photovoltaic applications, wear of MEMS and atomic force microscopy tips are just a few examples. In all these processes, friction and wear are strongly influenced by material transformations that are not fully understood as they occur at buried interfaces and are hardly accessible by in situ experiments.

In this seminar I will present the results of atomic-scale computer simulations that contribute to shed light on the tribological evolution of these two crystals. Interestingly, in spite of their common crystal structure and brittle behaviour, diamond and silicon can respond in completely different ways to tribological loads. First, I will show how both diamond and silicon can undergo shear-induced amorphization. The pressure-dependence of the amorphization rates is however opposite in the two materials. This is due to the opposite volume change upon shear-induced amorphization: carbon expands while silicon becomes denser. This can be related to the opposite slopes of the melting curves of diamond and diamond cubic silicon in their pressure-temperature phase diagram. Finally, I will present atomic-scale mechanisms for ultralow friction in water-lubricated diamond. It is known that water dissociative chemisorption can lead to surface passivation and low friction in both diamond and silicon. Our simulations show that water can also induce aromatic surface reconstructions that are responsible for ultralow friction in diamond and diamond-like carbon.

Large-scale real-space electronic structure calculations

In this talk, the development of a real-space formulation for Kohn-Sham density functional theory (DFT) and a finite-element discretization of this formulation [1,2], which can handle arbitrary boundary conditions and is amenable to adaptive coarse-graining, will be presented. In particular, the accuracy afforded by using higher-order and enriched finite-element discretizations, and the efficiency and scalability of the Chebyshev filtering algorithm in pseudopotential and all-electron Kohn-Sham DFT calculations will be demonstrated. Further, the development of a subquadratic-scaling approach (in the number of electrons) based on a subspace projection and Fermi-operator expansion will be discussed [3], which will be the basis for the future development of coarse-graining techniques for Kohn-Sham DFT. The developed techniques have enabled, to date, pseudopotential calculations on ~10,000 atoms, as well as all-electron calculations on systems containing ~10,000 electrons.
