Koopmon trajectories in nonadiabatic quantum-classical dynamics
Werner Bauer, Paul Bergold, François Gay-Balmaz +1
In order to alleviate the computational costs of fully quantum nonadiabatic dynamics, we present a mixed quantum-classical (MQC) particle method based on the theory of Koopman wave…

Multisymplectic variational integrators for barotropic and incompressible fluid models with constraints
François Demoures, François Gay-Balmaz
We present a structure preserving discretization of the fundamental spacetime geometric structures of fluid mechanics in the Lagrangian description in 2D and 3D. Based on this, mul…
