Modeling of quasiparticle-induced excitations of a Josephson charge-phase qubit

Autor: Könemann, J., Zangerle, H., Egeling, B., Harke, R., Mackrodt, B., Dolata, R., Zorin, A. B.

We have analyzed quasiparticle transitions in an Al charge-phase qubit inducing a dynamic change of the qubit states. The time-averaged mixed state is related to the strong coupling of the qubit to an ensemble of non-equilibrium quasiparticles in the

Quasi-particle transitions in charge-phase qubits probed by rf oscillations

Autor: Könemann, J., Zangerle, H., Mackrodt, B., Dolata, R., Zorin, A. B.

Publikováno v: Phys. Rev. B 76, 134507 (2007)

We investigated transitions in Al charge-phase qubits of SQUID-configuration inductively coupled to an rf tank circuit that made it possible to read out the state by measuring the inductance of the qubit. Depending on the flux and charge bias and the

Tunneling resonances in quantum dots: Coulomb interaction modifies the width

Autor: Könemann, J., Kubala, B., König, J., Haug, R. J.

Publikováno v: Phys. Rev. B 73, 033313 (2006)

Single-electron tunneling through a zero-dimensional state in an asymmetric double-barrier resonant-tunneling structure is studied. The broadening of steps in the $I$--$V$ characteristics is found to strongly depend on the polarity of the applied bia

Correlation-function spectroscopy of inelastic lifetime in heavily doped GaAs heterostructures

Autor: Könemann, J., König, P., Schmidt, T., McCann, E., Fal'ko, V. I., Haug, R. J.

Publikováno v: Phys. Rev. B 64, 155314 (2001)

Measurements of resonant tunneling through a localized impurity state are used to probe fluctuations in the local density of states of heavily doped GaAs. The measured differential conductance is analyzed in terms of correlation functions with respec

Measurement of the energy dependence of phase relaxation by single electron tunneling

Autor: König, P., Könemann, J., Schmidt, T., McCann, E., Fal'ko, V. I., Haug, R. J.

Single electron tunneling through a single impurity level is used to probe the fluctuations of the local density of states in the emitter. The energy dependence of quasi-particle relaxation in the emitter can be extracted from the damping of the fluc

Resonant tunneling through zero-dimensional impurity states: Effects of a finite temperature

Autor: König, P., Zeitler, U., Könemann, J., Schmidt, T., Haug, R. J.

We have performed temperature dependent tunneling experiments through a single impurity in an asymmetric vertical double barrier tunneling structure. In particular in the charging direction we observe at zero magnetic field a clear shift in the onset

A fluid queuing network constitutes one of the simplest models in which to study flow dynamics over a network. In this model we have a single source-sink pair and each link has a per-time-unit capacity and a transit time. A dynamic equilibrium (or eq
