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…
Full Quantum and Mixed Quantum--Classical Dynamics of Hot Exciton Cooling in Semiconductor Nanocrystals
Bokang Hou, Johan E. Runeson, Samuel L. Rudge +4
Hot-exciton relaxation in semiconductor nanocrystals (NCs) is often described using perturbative theories, but their accuracy is difficult to assess for realistic exciton--phonon H…
Vibrational Instabilities in Charge Transport through Molecular Nanojunctions: The Role of Anharmonic Nuclear Potentials
Martin Mäck, Michael Thoss, Samuel L. Rudge
The current-induced vibrational dynamics is a key factor determining the stability of molecular nanojunctions. Beyond conventional Joule heating, a different mechanism caused by no…
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…
