Intense-pulse dynamics of massless Dirac electrons
Hamed Koochaki Kelardeh, Ulf Saalmann, Jan M. Rost
We identify and describe how intense short light pulses couple to massless Dirac fermions in two-dimensional systems. The ensuing excitation dynamics exhibits unusual scaling with…
Full Counting Statistics of a Non-adiabatic Electron Pump
Alexander Croy, Ulf Saalmann
Non-adiabatic charge pumping through a single-level quantum dot with periodically modulated parameters is studied theoretically. By means of a quantum-master-equation approach the…
Non-adiabatic Rectification and Current Reversal in Electron Pumps
Alexander Croy, Ulf Saalmann
Pumping of electrons through nano-scale devices is one of the fascinating achievements in the field of nano-science with a wide range of applications. To optimize the performance o…
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…
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…
Coherent manipulation of charge qubits in double quantum dots
Alexander Croy, Ulf Saalmann
The coherent time evolution of electrons in double quantum dots induced by fast bias-voltage switches is studied theoretically. As it was shown experimentally, such driven double q…
Propagation Scheme for Non-Equilibrium Dynamics of Electron Transport in Nanoscale Devices
Alexander Croy, Ulf Saalmann
A closed set of coupled equations of motion for the description of time-dependent electron transport is derived. It provides the time evolution of energy-resolved quantities constr…
