Unraveling the Secrets of Matter through Ab Initio Molecular Dynamics

Ab Initio Molecular Dynamics (AIMD) is a powerful computational method that allows us to simulate and understand the behavior of atoms and molecules at the atomic level. By combining principles of molecular dynamics (MD) simulations with quantum mechanics, AIMD offers an unprecedented level of accuracy and detail, enabling researchers to explore the fundamental aspects of molecular systems.

How Does Ab Initio Molecular Dynamics Work?

AIMD relies on solving the time-dependent Schrödinger equation to obtain the electronic wavefunctions and energies, while simultaneously performing classical molecular dynamics calculations to describe the motion of the atomic nuclei. This combination allows for the dynamic simulation of molecular systems, providing insights into various phenomena such as chemical reactions, energy transfer, and structural changes.
