  3. 2. Mechanical and Electrical Properties of Mesoscopic Wires

    Författare :Sara Blom; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rabi oscillations; conductance quantization; free electron model; mesoscopic; microwave; channel; force fluctuations; adiabatic; nanowire;

    Sammanfattning : The mechanical and electrical properties of mesoscopic wires have been studied theoretically using a free electron model. When a mesoscopic wire is elongated the conductance decreases in steps. Each step is accompanied by an abrupt change in the force. LÄS MER

  5. 4. Coherent Far-Infrared Mode Pumping in Ballistic Electron Channels

    Författare :Ola Tageman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The influence of a high frequency electromagnetic field on transport properties of ballistic electron channels is investigated theoretically. We are primarily concerned with submicron-width channels formed by split-gate depletion of a two-dimensional electron gas at a GaAs/AlGaAs heterostructure interface. LÄS MER

  7. 5. Fast-tunable resonators and quantum electrical circuits

    Författare :Martin Sandberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SEB; tunable; Sisyphus resistance; CPW; Resonator; SCB; qubit; circuit-QED; transmon; SQUID;

    Sammanfattning : In this thesis, measurements on superconducting electrical circuits that exhibit quantum mechanical effects are presented. Nonlinear superconducting circuits can be regarded as artificial atoms with energy spectra that can be engineered. The artificial atoms can be used as quantum bits for quantum computation. LÄS MER
