Journal ArticleDOI

GPU-Accelerated Molecular Dynamics and Free Energy Methods in Amber18: Performance Enhancements and New Features.

TL;DR: Progress is reported in graphics processing unit (GPU)-accelerated molecular dynamics and free energy methods in Amber, including free energy perturbation and thermodynamic integration methods with support for nonlinear soft-core potential and parameter interpolation transformation pathways.
Journal ArticleDOI

Alchemical Binding Free Energy Calculations in AMBER20: Advances and Best Practices for Drug Discovery.

TL;DR: A contemporary overview of the scientific, technical, and practical issues associated with running relative BFE simulations in AMBER20 is provided, with a focus on real-world drug discovery applications.
Journal ArticleDOI

Charge-dependent model for many-body polarization, exchange, and dispersion interactions in hybrid quantum mechanical/molecular mechanical calculations.

TL;DR: A new model for nonelectrostatic nonbonded interactions in QMMM calculations that overcomes many of these problems is proposed, based on a scaled overlap model for repulsive exchange and attractive dispersion interactions that is a function of atomic charge.
Journal ArticleDOI

A variational linear-scaling framework to build practical, efficient next-generation orbital-based quantum force fields.

TL;DR: A new hybrid molecular orbital/density-functional modified divide-and-conquer (mDC) approach that allows the linear-scaling calculation of very large quantum systems and provides a powerful framework from which linear- scaling force fields for molecular simulations can be developed.
Journal ArticleDOI

Many-body force field models based solely on pairwise Coulomb screening do not simultaneously reproduce correct gas-phase and condensed-phase polarizability limits

TL;DR: It is demonstrated that many-body force field models based solely on pairwise Coulomb screening cannot simultaneously reproduce both gas-phase and condensed-phase polarizability limits, and that coupling with non-classical many- body effects, in particular exchange terms, may be important.
