Many-electron dynamics triggered by massively parallel ionization
Christian Gnodtke, Ulf Saalmann, Jan-Michael Rost
Massively parallel ionization of many atoms in a cluster or bio-molecule is identified as new phenomenon of light-matter interaction which becomes feasible through short and intens…
Non-adiabatic Electron Pumping through Interacting Quantum Dots
Alexander Croy, Ulf Saalmann, Alexis R. Hernández +1
We study non-adiabatic charge pumping through single-level quantum dots taking into account Coulomb interactions. We show how a truncated set of equations of motion can be propagat…
Energy bunching in soft recollisions revealed with long-wavelength few-cycle pulses
Alexander Kästner, Ulf Saalmann, Jan M. Rost
Soft recollisions are laser-driven distant collisions of an electron with its parent ion. Such collisions may cause an energy bunching, since electrons with different initial drift…
Electron-energy bunching in laser-driven soft recollisions
Alexander Kästner, Ulf Saalmann, Jan M. Rost
We introduce soft recollisions in laser-matter interaction. They are characterized by the electron missing the ion upon recollision in contrast to the well-known head-on collisions…
Propagation of Time-Nonlocal Quantum Master Equations for Time-Dependent Electron Transport
Alexander Croy, Ulf Saalmann
Time-resolved electron transport in nano-devices is described by means of a time-nonlocal quantum master equation for the reduced density operator. Our formulation allows for arbit…
