Scaling of level statistics at the metal-insulator transition
I. Kh. Zharekeshev, B. Kramer
Using the Anderson model for disordered systems the fluctuations in electron spectra near the metal--insulator transition were numerically calculated for lattices of sizes up to 28…
Transport through a one-dimensional quantum dot
T. Kleimann, M. Sassetti, G. Cuniberti +1
We examine the effects of long-range interactions in a quantum wire with two impurities. We employ the bosonization technique and derive an effective action for the system. The eff…
Dynamics of a large-spin-boson system in the strong coupling regime
T. Vorrath, T. Brandes, B. Kramer
We investigate collective effects of an ensemble of biased two level systems interacting with a bosonic bath in the strong coupling regime. The two level systems are described by a…
Control of spin in quantum dots with non-Fermi liquid correlations
Alessandro Braggio, Maura Sassetti, Bernhard Kramer
Spin effects in the transport properties of a quantum dot with spin-charge separation are investigated. It is found that the non-linear transport spectra are dominated by spin dyna…
Decay rate and renormalized frequency shift of a quantum wire Wannier exciton in a planar microcavity
Yueh-Nan Chen, Der-San Chuu, T. Brandes +1
The superradiant decay rate and frequency shift of a Wannier exciton in a one-dimensional quantum wire are studied. It is shown that the dark mode exciton can be examined experimen…
