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…
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…
A partial fraction decomposition of the Fermi function
Alexander Croy, Ulf Saalmann
A partial fraction decomposition of the Fermi function resulting in a finite sum over simple poles is proposed. This allows for efficient calculations involving the Fermi function…
Scaling at the Energy-driven Metal-Insulator Transition and the Thermoelectric Power
Alexander Croy, Rudolf A. Roemer
The electronic properties of disordered systems at the Anderson metal-insulator transition (MIT) have been the subject of intense study for several decades. Thermoelectric properti…
