We introduce JADE, a new software package for on-the-fly nonadiabatic dynamics simulations. JADE enables detailed studies of ultrafast photochemical processes in complex molecules using surface-hopping methods.
Area of Science:
- Computational Chemistry
- Quantum Chemistry
- Photochemistry
Background:
- Nonadiabatic dynamics simulations are crucial for understanding ultrafast photochemical processes.
- Simulating these processes in complex systems requires advanced computational tools.
Purpose of the Study:
- To present JADE, a novel on-the-fly nonadiabatic dynamics simulation package.
- To enable all-atomic level simulations of excited-state dynamics in polyatomic systems.
Main Methods:
- Utilizes Tully's surface-hopping approach for nonadiabatic dynamics.
- Supports various electronic structure methods including TDDFT.
- Interfaced with popular quantum chemistry codes (Turbomole, Gaussian, Gamess).
- Incorporates Langevin dynamics for environmental effects.
Main Results:
- Demonstrates JADE's capability through simulations of methaniminium cation, C20, DMABN, ABN, and 10-HBQ.
- Highlights the package's performance and flexibility for medium- to large-sized molecules.
Conclusions:
- JADE is an open-source, user-friendly software for photochemical and photophysical simulations.
- The package facilitates detailed investigations of excited-state dynamics.

Molecular and Ionic Solids
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
