Tunneling through nanosystems: Combining broadening with many-particle states
Jonas Nyvold Pedersen, Andreas Wacker
We suggest a new approach for transport through finite systems based on the Liouville equation. By working in a basis of many-particle states for the finite system, Coulomb interac…
Self-Consistent Theory of the Gain Linewidth for Quantum Cascade Lasers
F. Banit, S. -C. Lee, A. Knorr +1
The linewidth in intersubband transitions can be significantly reduced below the sum of the lifetime broadening for the involved states, if the scattering environment is similar fo…
Positive Correlations in Tunneling through coupled Quantum Dots
H. Sprekeler, G. Kiesslich, A. Wacker +1
Due to the Fermi-Dirac statistics of electrons the temporal correlations of tunneling events in a double barrier setup are typically negative. Here, we investigate the shot noise b…
A hybrid model for chaotic front dynamics: From semiconductors to water tanks
A. Amann, K. Peters, U. Parlitz +2
We present a general method for studying front propagation in nonlinear systems with a global constraint in the language of hybrid tank models. The method is illustrated in the cas…
Shot Noise in Tunneling through a Quantum Dot Array
G. Kiesslich, A. Wacker, E. Schoell +3
The shot noise suppression in a sample containing a layer of self-assembled InAs quantum dots has been investigated experimentally and theoretically. The observation of a non-monot…
Chaotic front dynamics in semiconductor superlattices
A. Amann, J. Schlesner, A. Wacker +1
We analyze the dynamical evolution of the current and the charge density in a superlattice for fixed external dc voltage in the regime of self-sustained current oscillations, using…
