CP2K is a versatile open-source software package for simulations across a wide range of atomistic systems, from isolated molecules in the gas phase to low-dimensional functional ma…
Introduction to machine learning potentials for atomistic simulations
Fabian L. Thiemann, Niamh O'Neill, Venkat Kapil +2
Machine learning potentials have revolutionised the field of atomistic simulations in recent years and are becoming a mainstay in the toolbox of computational scientists. This pape…
Protons accumulate at the graphene-water interface
Xavier R. Advincula, Kara D. Fong, Angelos Michaelides +1
Water's ability to autoionize into hydroxide and hydronium ions profoundly influences surface properties, rendering interfaces either basic or acidic. While it is well-established…
The Wetting of HO by CO
Samuel G. H. Brookes, Venkat Kapil, Christoph Schran +1
Biphasic interfaces are complex but fascinating regimes that display a number of properties distinct from those of the bulk. The CO-HO interface, in particular, has been th…
A foundation model for atomistic materials chemistry
Ilyes Batatia, Philipp Benner, Yuan Chiang +85
Atomistic simulations of matter, especially those that leverage first-principles (ab initio) electronic structure theory, provide a microscopic view of the world, underpinning much…
Quasi-one-dimensional hydrogen bonding in nanoconfined ice
Pavan Ravindra, Xavier R. Advincula, Christoph Schran +2
The Bernal-Fowler ice rules stipulate that each water molecule in an ice crystal should form four hydrogen bonds. However, in extreme or constrained conditions, the arrangement of…
To Pair or not to Pair? Machine-Learned Explicitly-Correlated Electronic Structure for NaCl in Water
Niamh O'Neill, Benjamin X. Shi, Kara Fong +2
The extent of ion pairing in solution is an important phenomenon to rationalise transport and thermodynamic properties of electrolytes. A fundamental measure of this pairing is the…
Understanding the anomalously low dielectric constant of confined water: an ab initio study
Thomas Dufils, Christoph Schran, Ji Chen +3
Recent experiments have shown that the out-of-plane dielectric constant of water confined in nanoslits of graphite and hexagonal boron nitride (hBN) is vanishingly small. Despite e…
Crumbling Crystals: On the Dissolution Mechanism of NaCl in Water
Niamh O'Neill, Christoph Schran, Stephen J. Cox +1
Life on Earth depends upon the dissolution of ionic salts in water, particularly NaCl. However, an atomistic scale understanding of the process remains elusive. Simulations lend th…

Henrik R. Larsson, Markus Schröder, Richard Beckmann +4
The infrared (IR) spectra of protonated water clusters encode precise information on the dynamics and structure of the hydrated proton. However, the strong anharmonic coupling and…
Tracking single atoms in a liquid environment
Nicholas Clark, Daniel J. Kelly, Mingwei Zhou +7
The chemical behaviour of single metal atoms largely depends on the local coordination environment, including interactions with the substrate and with the surrounding gas or liquid…
