Modelling long-range interactions in multiscale simulations of ferromagnetic materials
Atomistic-continuum multiscale modelling is becoming an increasingly popular tool for simulating the behaviour of materials due to its computational efficiency and reliable accuracy. In the case of ferromagnetic materials, the atomistic approach handles th ...
SPRINGER2020Predicting molecular dipole moments by combining atomic partial charges and atomic dipoles
Michele Ceriotti, David Mark Wilkins, Max David Veit, Yang Yang
The molecular dipole moment (mu) is a central quantity in chemistry. It is essential in predicting infrared and sum-frequency generation spectra as well as induction and long-range electrostatic interactions. Furthermore, it can be extracted directly-via t ...
AMER INST PHYSICS2020Incorporating long-range physics in atomic-scale machine learning
Michele Ceriotti, Andrea Grisafi
The most successful and popular machine learning models of atomic-scale properties derive their transferability from a locality ansatz. The properties of a large molecule or a bulk material are written as a sum over contributions that depend on the configu ...
2019Controlling the bias error of Fokker- Planck methods for rarefied gas dynamics simulations
Direct simulation Monte-Carlo (DSMC) is the most established method for rarefied gas flow simulations. It is valid from continuum to near vacuum, but in cases involving small Knudsen numbers (Kn), it suffers from high computational cost. The Fokker-Planck ...
2019Improving Performance and Accuracy of Hybrid-Functional Based Molecular Dynamics in Plane Waves
The simulation of condensed matter in first principles Molecular Dynamics (FPMD) heavily relies on Kohn-Sham Density Functional Theory (KS-DFT) calculations. The accuracy of such simulations is governed by the reliability of the underlying potential energy ...
EPFL2018Density functional perturbation theory for gated two-dimensional heterostructures: Theoretical developments and application to flexural phonons in graphene
The ability to perform first-principles calculations of electronic and vibrational properties of two-dimensional heterostructures in a field-effect setup is crucial for the understanding and design of next-generation devices. We present here an implementat ...
Amer Physical Soc2017Two-dimensional Frohlich interaction in transition-metal dichalcogenide monolayers: Theoretical modeling and first-principles calculations
We perform ab initio calculations of the coupling between electrons and small-momentum polar-optical phonons in monolayer transition-metal dichalcogenides of the 2H type: MoS2, MoSe2, MoTe2, WS2, and WSe2. The polar-optical coupling with longitudinal optic ...
Amer Physical Soc2016Controlling the Long-Range Corrections in Atomistic Monte Carlo Simulations of Two-Phase Systems
The long-range correction to the surface tension can amount to up to 55% of the calculated value of the surface tension for cutoffs in the range of 2.1-6.4 sigma. The calculation of the long-range corrections to the surface tension and to the configuration ...
Amer Chemical Soc2015Heterogeneity of AMPA receptor trafficking and molecular interactions revealed by superresolution analysis of live cell imaging
Suliana Manley, Christian Sieben
Simultaneous tracking of many thousands of individual particles in live cells is possible now with the advent of high-density superresolution imaging methods. We present an approach to extract local biophysical properties of cell-particle interaction from ...
