Materials Modeling with the Amsterdam Modeling Suite

Material properties are ultimately determined at the atomistic level. The Amsterdam Modeling Suite provides a user-friendly, powerful set of computational chemistry tools to study electronic and optical properties, chemical reactivity and mechanical behavior. We introduce our DFT, DFTB and ReaxFF modules and demo the excellent graphical interface. Recent examples from various material science applications in the fields of batteries, organic electronics, and nanotechnology will show how your research can be advanced. The slides and video of the materials modeling web presentation are available.

Optical and X-ray absorption spectra with ADF

Presenter: Mauro Stener, University of Trieste
Description: Mauro discusses ADF’s attractive features for calculating optical properties of large nanoparticles. Recent efforts to further increase TDDFT efficiency pave the way for studying even larger nanoparticles, such as large ligand-capped metal clusters. Mauro also discusses how ADF’s spin-orbit-TDDFT and Slater-TS methods can be used to accurately and efficiently calculate X-ray absorption spectra (NEXAFS, XANES). A few hands-on examples are shown to help you with calculating your own UV/VIS and X-ray spectra with ADF. Optical_Spectrum_Silver_Nanoparticles

Charge mobility, energy transfer with Frozen-Density Embedding

Presenter: Michele Pavanello, Rutgers University
Description: Michele actively develops subsystem DFT for accurately describing charge and excitation energy transfer dynamics in complex systems. Charges, excitons, and spins are localized on particular subsystems within the linear-scaling FDE formulation in ADF. Coupling between these diabatic states are related to charge mobility, energy transfer, charge separation and other processes important in organic electronics and photovoltaics. Michele introduces FDE theory and shows some hands-on examples. HoleTransferTiophene

QUILD: flexible multi-level optimization tool

Presenter: Marcel Swart
Description: QUILD (QUantum-regions Interconnected by Local Descriptions) features enhanced optimization routines for running multi-level calculations. Marcel introduces the concepts behind QUILD and shows how easy it is to set up subtractive multi-layer QM/MM and QM/QM calcalutions, including how to use QUILD to remove spin contamination from energies, forces and frequencies.

Multi-scale and adaptive molecular dynamics with FlexMD

Presenter: Rosa Bulo
Description: FlexMD is a flexible tool for running multi-scale (QM/MM and QM/QM) molecular dynamics. The python library is interfaced with all modules from the Amsterdam Modeling Suite as well with the Atomistic Simulation Environment and PLUMED. Rosa briefly discussed the different adaptive multi-scale MD schemes implemented in FlexMD and gave live demonstrations on how to set up, run and analyze calculations. FlexMD_S

Optimizing ReaxFF parameters with MMC-SA

Presenter: Eldhose Iype
Description: ReaxFF is a powerful tool to study the chemical evolution of large, complex systems. Parametrization becomes increasingly complex for systems with many elements, owing to the many bond-length dependent and cross terms. Eldhose Iype demonstrated the Metropolis Monte Carlo with Simulated annealing (MMC-SA) global optimization technique for fast and automated optimization of ReaxFF parameters given a set of benchmark (DFT) data. He gave a hands-on example and discussed pitfalls, e.g. the need for a good training set that adequately represents the chemical space during the reactive dynamics. New tools that will help parametrization (e.g. converting xyz files to geo format) will soon become available in the development versions of ADF. TiO2_nanocrystal_growth_Square
