Adiabatically-induced Kawaguchi geometry and jerk in quantum-classical systems
Athanasios Chatzistavrakidis, Larisa Jonke, Ryan Requist
Adiabatically eliminating the quantum degrees of freedom in a mixed quantum-classical system produces an effective force in the classical equation of motion. The elimination can be…

Adiabatic perturbation theory for two-component systems with one heavy component
Ryan Requist
Perturbation theory with respect to the kinetic energy of the heavy component of a two-component quantum system is introduced. An effective Hamiltonian that is accurate to second o…
