  1. 1. Quantum optics with artificial atoms

    Författare :Anton Frisk Kockum; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface acoustic waves; transmon; circuit QED; photon detector; parity measurement; quantum stochastic calculus; Quantum optics; artificial atoms; quantum measurement;

    Sammanfattning : Quantum optics is the study of interaction between atoms and photons. In the eight papers of this thesis, we study a number of systems where artificial atoms (here, superconducting circuits emulating the level structure of an atom) enable us to either improve on known concepts or experiments from quantum optics with natural atoms, or to explore entirely new regimes which have not been possible to reach in such experiments.

  2. 2. Ultracold atoms in optical potentials : from noise-induced transport to superfluidity

    Författare :Martin Zelan; Claude Dion; Sile Nic Chormaic; Umeå universitet; []
    Nyckelord :Brownian motors; noise-induced transport; superfluidity; ultracold atoms; optical potentials; optical lattices; laser coooling; fysik; Physics;

    Sammanfattning : In this thesis, both experimental studies and numerical simulations of ultracold atoms in optical potentials are presented in a collection of nine scientific papers. In particular, noise-induced transport in dissipative optical lattices and superfluid properties of Bose-Einstein condensates have been studied. LÄS MER

  4. 4. Experimental and Numerical Investigations of Ultra-Cold Atoms

    Författare :Magnus Rehn; Anders Kastberg; Claude Dion; Matti Kaivola; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Ultracold atoms; optical lattices; Bose-Einstein condensation; quantum phase transitions; Physics; Fysik;

    Sammanfattning : I have been one of the main responsible for building a new laboratory for Bose-Einstein condensation with 87Rb. In particular, the experimental setup has been designed for performing experiments with Bose-Einstein condensates load into optical lattices of variable geometries. All parts essential for Bose-Einstein condensation are in place. LÄS MER

  5. 5. Molecular-dynamics simulations of polymeric surfaces for biomolecular applications

    Författare :Stela Andrea Muntean; M.A.J. Michels; M.W.J. Prins; A.V. Lyulin; Technische Universiteit Eindhoven; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Polystyrenes; Molecular Dynamics; Computer Simulation; Water; Molecules; Atoms; Hydrophilicity; Biosensors; Myoglobin; Physics; Fysik;

    Sammanfattning : In-vitro diagnostics plays a very important role in the present healthcare system. It consists of a large variety of medical devices designed to diagnose a medical condition by measuring a target molecule in a sample, such as blood or urine. LÄS MER
