21. Thermoelectric experiments on nanowire-based quantum dots
Sammanfattning : This thesis experimentally investigates the possibilities of using quantum effects in semiconductor nanostructures for engineering their thermoelectric properties. More specifically, heterostructured InAs/InP nanowires are used to create short InAs quantum dots (QDs) with electronic state structure resembling that found in atoms. LÄS MER
22. Azimuthal Correlations in Dijet Events from Deep Inelastic Positron-Proton Scattering at HERA
Sammanfattning : Correlations in the azimuthal angle between dijets produced in deep inelastic $e^{+}p$ scattering events, collected by the H1 experiment during 1999-2000, have been investigated. Cross sections are presented as a function of the azimuthal separation between the two jets in the hadronic center of mass frame, $Deltaphi^{*}$, in different regions of the photon virtuality $Q^{2}$ and in different regions of the Bjorken scaling variable $x_{Bj}$.

23. Quantum Materials Probed by Light and Electron Spectroscopy
Sammanfattning : As new technologies rely heavily on materials’ properties, the quest for novel tunable electronic and magnetic materials occupies a large part of nowadays research efforts. Most promising materials are quantum materials, which exhibit a wide range of exotic electronic and magnetic phenomena and often show a great sensitivity to external perturbations such as temperature, pressure or chemical doping.

24. Classical and Quantum Descriptions of Proteins, Lipids and Membranes
Sammanfattning : In this thesis the properties of proteins and membranes are studied by molecular dynamics simulations. The subject is decomposed into parts addressing free energy calculations in proteins, mechanical inclusion models for lipid bilayers, phase transitions and structural correlations in lipid bilayers and atomistic lipid bilayer models.

25. High visibility six-photonentanglement
Sammanfattning : Entanglement is a key resource in many quantum information schemes andin the last years the research on multi-qubit entanglement has drawn lots ofattention. In this thesis the experimental generation and characterization ofmulti-qubit entanglement is presented. LÄS MER
