MANDALA: An E(3)-Equivariant Graph Neural Network Framework for Learning Electronic-Structure Operators with Observable Guidance
Bartosz Brzoza, Wiktoria Szopa, Zakaria Elabid +5
Electronic-structure calculations based on Kohn-Sham density functional theory remain indispensable in computational materials science and chemistry. Their computational cost, howe…
CP2K: An electronic structure and molecular dynamics software package - Dynamics, Transport, and Spectroscopic Response
Jan Wilhelm, Anna-Sophia Hehn, Anna Hehn +40
One of the distinguishing aspects of CP2K is its seamless integration of diverse structural and transition-state optimization techniques with advanced sampling approaches including…
Accelerated "on-the-fly" coupled-cluster path-integral molecular dynamics: Impact of nuclear quantum effects on an asymmetric proton
Thomas Spura, Hossam Elgabarty, Thomas D. Kühne
We present an accelerated ``on-the-fly'' coupled-cluster path-integral molecular dynamics (PIMD) method for finite-temperature simulations in which electron correlation and nuclear…
Predicting the hydrogen bond strength from water reorientation dynamics at short timescales
Frederik Zysk, Ana Vila Verde, Naveen K. Kaliannan +2
Path-integral molecular dynamics simulations and electronic structure-based energy decomposition analysis (EDA) are employed to connect hydrogen bond (H-bond) strength, its asymmet…
The CP-PAW code package for first-principles calculations from a user's perspective
Peter E. Blöchl, Robert Schade, Lukas Allen-Rump +5
CP-PAW is a combined electronic structure and ab-initio molecular dynamics code to perform mixed quantum and classical simulations of atomistic condensed phase systems, such as sol…
Scalable Machine Learning Model for Energy Decomposition Analysis in Aqueous Systems
Hossein Tahmasbi, Michael Beerbaum, Bartosz Brzoza +2
Energy decomposition analysis (EDA) based on absolutely localized molecular orbitals provides detailed insights into intermolecular bonding by decomposing the total molecular bindi…
