  1. 1. Generation of coherent short-wavelength radiation --- High-order harmonics and x-ray lasers

    Författare :Tomas Starczewski; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; short-wavelength radiation; coherence; high-intensity lasers; high-order harmonics; x-ray lasers; Atom- och molekylärfysik;

    Sammanfattning : The recent availability of short-pulse, high-intensity, compact lasers has opened doors to new and fascinating areas in atomic physics. Using the Lund Terawatt Laser, the interaction of femtosecond, near-infrared and visible laser radiation with matter at intensities in the range 1013--1017 W/cm2 was studied. LÄS MER

  5. 4. Quantum acoustics with superconducting circuits

    Författare :Gustav Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; superconducting qubits; cluster states; SAW; two-level systems; circuit QED; giant atoms; two-mode squeezing; surface acoustic wave; quantum acoustics; hybrid quantum systems;

    Sammanfattning : The past 20 years has seen rapid developments in circuit quantum electrodynamics, where superconducting qubits and resonators are used to control and study quantum light-matter interaction at a fundamental level. The development of this field is strongly influenced by quantum information science and the prospect of realizing quantum computation, but also opens up opportunities for combinations of different physical systems and research areas.

  7. 5. X-ray - Based Studies of Structural Dynamics in Solids and Liquids

    Författare :Ralf Nüske; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The wavelength of x-ray radiation is much shorter than that of visible light. In fact, it is comparable to the distances between atoms in solids, which is on the order of one tenth of a nanometer. Using light of such a short wavelength, it is possible to study the structure of materials on the atom level. LÄS MER
