Negative Electronic Friction and Non-Markovianity in Nonequilibrium Quantum Systems
Riley J. Preston, Samuel L. Rudge, Daniel S. Kosov +1
We address the connection between negative electronic friction and non-Markovian effects in the nonadiabatic vibrational dynamics of molecules interacting with metal surfaces under…
A Haldane-Anderson Hamiltonian Model for Hyperthermal Hydrogen Scattering from a Semiconductor Surface
Xuexun Lu, Nils Hertl, Sara Oregioni +5
Collisions of atoms and molecules with metal surfaces create electronic excitations in the metal, leading to nonadiabatic energy dissipation, inelastic scattering, and sticking. Mi…
Vibrational Instabilities in Charge Transport through Molecular Nanojunctions: The Role of Nonconservative Current-Induced Electronic Forces
Martin Mäck, Riley J. Preston, Michael Thoss +1
Understanding the current-induced vibrational dynamics in molecular nanojunctions is critical for gaining insight into the stability of such systems. While it is well known that Jo…
The Role of Quantum Vibronic Effects in the Spin Polarization of Charge Transport through Molecular Junctions
Samuel L. Rudge, Christoph Kaspar, Rudolf Smorka +3
The connection between molecular vibrations and spin polarization in charge transport through molecular junctions is currently a topic of high interest, with important consequences…
Nonadiabatic Quantum Dynamics of Molecules Scattering from Metal Surfaces
Riley J. Preston, Yaling Ke, Samuel L. Rudge +4
Nonadiabatic coupling between electrons and molecular motion at metal surfaces leads to energy dissipation and dynamical steering effects during chemical surface dynamics. We prese…
