Electron conductivity and second generation Composite Fermions
Matteo Merlo, Nicodemo Magnoli, Maura Sassetti +1
The relation between the conductivity tensors of Composite Fermions and electrons is extended to second generation Composite Fermions. It is shown that it crucially depends on the…
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…
Transport in quantum wires with impurities at finite temperatures
T. Kleimann, M. Sassetti, B. Kramer
The temperature dependence of Coulomb blockade peaks of a one dimensional quantum dot is calculated. The Coulomb interaction is treated microscopically using the Luttinger liquid m…
New selection rules for resonant Raman scattering on quantum wires
E. Mariani, M. Sassetti, B. Kramer
The bosonisation technique is used to calculate the resonant Raman spectrum of a quantum wire with two electronic sub-bands occupied. Close to resonance, the cross section at frequ…
Tomonaga-Luttinger features in the resonant Raman spectra of quantum wires
B. Kramer, M. Sassetti
The differential cross section for resonant Raman scattering from the collective modes in a one dimensional system of interacting electrons is calculated non-perturbatively using t…
Sum rule for transport in a Luttinger liquid with long range interaction in the presence of an impurity
Gianaurelio Cuniberti, Maura Sassetti, Bernhard Kramer
We show that the non-linear dc transport in a Luttinger liquid with interaction of finite range in the presence of an impurity is governed by a sum rule which causes the charging e…
Coulomb blockade at a tunnel junction between two quantum wires with long-range interaction
Maura Sassetti, Gianaurelio Cuniberti, Bernhard Kramer
The non-linear current-voltage characteristic of a tunnel junction between two Luttinger systems is calculated for an interaction with finite range. Coulomb blockade features are f…
Exact density of states of a two-dimensional electron gas in a strong magnetic field and a long-range correlated random potential
Lothar Spies, Walter Apel, Bernhard Kramer
We derive an exact result for the averaged Feynman propagator and the corresponding density of states of an electron in two dimensions in a perpendicular homogeneous magnetic field…
Crossover of Level Statistics between Strong and Weak Localization in Two Dimensions
I. Kh. Zharekeshev, M. Batsch, B. Kramer
We investigate numerically the statistical properties of spectra of two-dimensional disordered systems by using the exact diagonalization and decimation method applied to the Ander…
Scaling Behavior of Level Statistics in Quantum Hall Regime
Y. Ono, T. Ohtsuki, B. Kramer
The scaling property of level statistics in the quantum Hall regime, i.e. 2D disordered electron systems subject to strong magnetic fields, is analyzed numerically in the light of…
Signatures of electron correlations in the transport properties of quantum dots
Kristian Jauregui, Wolfgang Häusler, Dietmar Weinmann +1
The transition matrix elements between the correlated and electron states of a quantum dot are calculated by numerical diagonalization. They are the central ingredien…
