Description This Consortium grant provides access to the UK's most powerful supercomputer to a group of researchers across many institutions with the collective aim of applying novel computational methods to key scientific questions: these range from creating new machine learning methods to accelerate materials computations, applied dense hydrogen and silicon, to pushing first principles structure prediction methods to complex chemistries, such at those found in potential new battery cathode materials. Given the volume of work that this grant has supported, it would be true to say that it has shifted the state of the art across a wide range of fields.
Exploitation Route CASTEP, a key UKCP code, is sold commercially by Dassault Systemes, but has recently been made available at no cost to the entire global research community. Other codes, such as AIRSS and SHEAP are available under open source licenses.

Title Finite field formalism for bulk electrolyte solutions (data set) 
Description All simulations can be run with the LAMMPS code (22 Sept 2017). See also https://github.com/uccasco/FiniteFields for additional source code required to apply the constant D ensemble. Constant E simulations can be performed with in.SPCE.efield. The user will need to replace with the appropriate value of E (along the z direction). Constant D simulations can be performed with in.SPCE.dfield. Likewise, the user will need to replace with the appropriate value of D. Also included are configurations corresponding to different concentrations (these have been obtained from D = 0 simulations). The number of ions pairs and water molecules is given by the filename e.g. 10pair_256wat.data contains 10 ion pairs and 256 water molecules. The name of the configuration file will need to replace the text "" on line 13 of the input files. Note the user may wish to perform shorter simulations for equilibration purposes, especially when changing the value of Dz, or switching to the E ensemble. See included README file.

Title Stabilization of AgI's polar surfaces by the aqueous environment, and its implications for ice formation (data set) 
Description See also the README file. This dataset contains three sub-directories: (1) D0o0 -- contains input files for performing simulations at D = 0 (2) DCNC -- contains input files for performing simulations at DCNC (2) ECNC -- contains input files for performing simulations at ECNC All simulations can be run with the LAMMPS code (16 Mar 2018). See also https://github.com/uccasco/FiniteFields for additional source code required to apply the E and D fields. Each directory contains the followings files: (a) init.data -- initial structure for pure water in contact with AgI. (b) in.tip4p2005.equil -- input file for performing the initial equilibration of the system at 252K. (c) in.tip4p2005.cool -- input file for performing the cooling ramp simulation between 252K and 242K. (d) in.tip4p2005.constT -- input file for performing a constant T simulation at 242K. The above files perform simulations with an immobile AgI crystal. The DCNC additionally contains a file "in.tip4p2005.constT.mob" which demonstrates the changes needed to perform a simulation with a mobile AgI crystal. (The other equilibration and cooling input files can be similarly adapted.) The ECNC and DCNC directories also contain a file "init.data.electrolyte" which contains an initial structure for NaCl electrolyte in contact with AgI. Please see Table S1 of the article for values of D and E fields used. AgI.table -- tabulated interatomic potential for AgI crystal.

Title AIRSS 
Description Ab initio Random Structure Searching (AIRSS) is a very simple, yet powerful and highly parallel, approach to structure prediction. The concept was introduced in 2006 and its philosophy more extensively discussed in 2011. Random structures - or more precisely, random "sensible" structures - are generated and then relaxed to nearby local energy minima. Particular success has been found using density functional theory (DFT) for the energies, hence the focus on "ab initio" random structure searching. The sensible random structures are constructed so that they have reasonable densities, and atomic separations. Additionally they may embody crystallographic, chemical or prior experimental/computational knowledge. Beyond these explicit constraints the emphasis is on a broad, uniform, sampling of structure space. AIRSS has been used in a number of landmark studies in structure prediction, from the structure of SiH4 under pressure to providing the theoretical structures which are used to understand dense hydrogen (and anticipating the mixed Phase IV), incommensurate phases in aluminium under terapascal pressures, and ionic phases of ammonia. The approach naturally extends to the prediction clusters/molecules, defects in solids, interfaces and surfaces (interfaces with vacuum). The AIRSS package is tightly integrated with the CASTEP first principles total energy code. However, it is relatively straightforward to modify the scripts to use alternative codes to obtain the core functionality, and examples are provided. The AIRSS package is released under the GPL2 licence.

Title Stochastic Hyperspace Embedding and Projection (SHEAP) 
Description Stochastic Hyperspace Embedding And Projection (SHEAP) is a dimensionality reduction method designed for visualising potential energy surfaces. Computational structure prediction can assist the discovery of new materials. One searches for the most stable configurations of a given set of atomic building blocks, which correspond to the deepest regions of an energy landscape-the system's energy as a function of the relative positions of its atoms. To explore these landscapes efficiently, it is important to understand their topologies. However, they exist in spaces with very large numbers of dimensions, making them difficult to visualise. SHEAP uses dimensionality reduction through manifold learning to effectively visualise the distribution of stable structures across a high-dimensional energy landscape.

Impact The SHEAP code is being routinely used in our structure searches to map the energy landscape, and help to steer the searches.
