General comments
The Atomistic Simulation of Carbon and related Materials (ASCM2019) workshop (ascm2019.nanocarbon.fi) took place in Helsinki, Finland between the 10th and 12th of April 2019. The workshop venue was the historical main building of the University of Helsinki. The event was jointly organized by Flyura Djurabekova (University of Helsinki), Volker Deringer (University of Cambridge) and Miguel Caro (Aalto University).
A total of circa 45 participants (mostly from Europe but also from overseas) met at the heart of Helsinki for three days of discussion on the state of the art and future prospects of atomistic simulation of pure carbon compounds and nanostructures, functionalized carbon materials, carbon-containing molecules and silicon/SiC alloys. Focus topics with strong presence at the workshop were atomistic modeling of graphene and carbon nanotubes, amorphous carbon, molecular dynamics simulations of high-energy/irradiation effects, development and benchmarking of interatomic potentials and, prominently, machine learning applied to atomistic simulations in general and carbon science in particular. The oral sessions featured a nice combination of established and early-career researchers.
While density-functional-theory-based methods are still predominant in the community, the importance of van der Waals corrections (especially important for carbon nanostructures) and the acceleration of molecular dynamics through machine learning are gaining prominence. In particular, the main application of machine learning methodologies is the interpolation of potential energy surfaces, but also other applications, such as for data classification and visualization are starting to take root. Simulation of spectroscopic techniques, namely Raman, NMR and X-ray spectroscopies, is also gaining momentum for verifying and predicting structural models of materials. Finally, multiscale modeling where different levels of theory are mixed (e.g., to parametrize atomistic force fields from electronic structure calculations) retains its validity, in particular in the wake of machine learning potentials which feed on ab initio data.
Funding
The workshop was funded by the Finnish CECAM node, the Psi-K Network, Aalto University’s CMMP network and University of Helsinki’s MATRENA. In addition, the Aalto University Materials Platform sponsored “best talk” and “best poster” prizes.
