Strain-displacement relations and strain engineering in 2d materials
Daniel Midtvedt, Caio H. Lewenkopf, Alexander Croy
We investigate the electromechanical coupling in 2d materials. For non-Bravais lattices, we find important corrections to the standard macroscopic strain - microscopic atomic-displ…
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…
Pseudomodes and the corresponding transformation of the temperature-dependent bath correlation function
David W. Schönleber, Alexander Croy, Alexander Eisfeld
In open system approaches with non-Markovian environments, the process of inserting an individual mode (denoted as "pseudomode") into the bath or extracting it from the bath is wid…
Strain-tuning of vacancy-induced magnetism in graphene nanoribbons
Daniel Midtvedt, Alexander Croy
Vacancies in graphene lead to the appearance of localized electronic states with non-vanishing spin moments. Using a mean-field Hubbard model and an effective double-quantum dot de…
