Dicke Effect in the Tunnel Current through two Double Quantum Dots
T. Vorrath, T. Brandes
We calculate the stationary current through two double quantum dots which are interacting via a common phonon environment. Numerical and analytical solutions of a master equation i…
Single electron-phonon interaction in a suspended quantum dot phonon cavity
E. M. Höhberger, R. H. Blick, T. Brandes +4
An electron-phonon cavity consisting of a quantum dot embedded in a free-standing GaAs/AlGaAs membrane is characterized in Coulomb blockade measurements at low temperatures. We fin…
Adiabatic Transfer of Electrons in Coupled Quantum Dots
T. Brandes, T. Vorrath
We investigate the influence of dissipation on one- and two-qubit rotations in coupled semiconductor quantum dots, using a (pseudo) spin-boson model with adiabatically varying para…
Control of Dephasing and Phonon Emission in Coupled Quantum Dots
S. Debald, T. Brandes, B. Kramer
We predict that phonon subband quantization can be detected in the non-linear electron current through double quantum dot qubits embedded into nano-size semiconductor slabs, acting…
Charge transport through quantum dots via time-varying tunnel couplings
F. Renzoni, T. Brandes
We describe a novel mechanism for charge pumping through tunnel-coupled quantum dots in the regime of strong Coulomb blockade. The quantum state of an additional electron within th…
Adiabatic steering and determination of dephasing rates in double dot qubits
T. Brandes, F. Renzoni, R. H. Blick
We propose a scheme to prepare arbitrary superpositions of quantum states in double quantum--dots irradiated by coherent microwave pulses. Solving the equations of motion for the d…
