Natural Quantum Monte Carlo Computation of Excited States

2 code implementations31 Aug 2023 David Pfau, Simon Axelrod, Halvard Sutterud, Ingrid von Glehn, James S. Spencer

We present a variational Monte Carlo algorithm for estimating the lowest excited states of a quantum system which is a natural generalization of the estimation of ground states.

Excited state, non-adiabatic dynamics of large photoswitchable molecules using a chemically transferable machine learning potential

no code implementations10 Aug 2021 Simon Axelrod, Eugene Shakhnovich, Rafael Gómez-Bombarelli

For example, photoisomerization can allow a drug with a photo-switchable scaffold such as azobenzene to be activated with light.

Molecular machine learning with conformer ensembles

1 code implementation15 Dec 2020 Simon Axelrod, Rafael Gomez-Bombarelli

Here we investigate how the 3D information of multiple conformers, traditionally known as 4D information in the cheminformatics community, can improve molecular property prediction in deep learning models.

Temperature-transferable coarse-graining of ionic liquids with dual graph convolutional neural networks

2 code implementations28 Jul 2020 Jurgis Ruza, Wujie Wang, Daniel Schwalbe-Koda, Simon Axelrod, William H. Harris, Rafael Gomez-Bombarelli

The potential of mean force is expressed as two jointly-trained neural network interatomic potentials that learn the coupled short-range and the many-body long range molecular interactions.

GEOM: Energy-annotated molecular conformations for property prediction and molecular generation

2 code implementations9 Jun 2020 Simon Axelrod, Rafael Gomez-Bombarelli

The Geometric Ensemble Of Molecules (GEOM) dataset contains conformers for 133, 000 species from QM9, and 317, 000 species with experimental data related to biophysics, physiology, and physical chemistry.

Differentiable Molecular Simulations for Control and Learning

2 code implementations ICLR Workshop DeepDiffEq 2019 Wujie Wang, Simon Axelrod, Rafael Gómez-Bombarelli

From the perspective of engineering, one wishes to control the Hamiltonian to achieve desired simulation outcomes and structures, as in self-assembly and optical control, to then realize systems with the desired Hamiltonian in the lab.
