  1. Quanteneffekte in nanomechanischen Systemen

    … untersucht. Dabei werden zunaechst Quantenfluktuationen der transversalen Auslenkung des Resonators behandelt. Diese lassen sich durch zwei Verfahren verstaerken, dynamisch mittels parametrischer Resonanz, oder statisch durch longitudinale Kompression bis nahe der …

  2. Stochastic cosmological inflation : a replica field-theoretical study

    … einen Rahmen zur Verfügung, in welchem beliebige Quantenfluktuationen behandelt werden können, und könnten ein Startpunkt sein, um Rückwirkungseffekte bezüglich der Geometrie der Raumzeit einzubeziehen. Einführungen in kosmologische Inflation, kosmologische Störungstheorie und Anisotropien des …

  3. Aspects of Quantum Fluctuations under Time-dependent External Influences

    The vacuum of quantum field theory is not empty space but filled with quantum vacuum fluctuations, which give rise to many intriguing effects. The first part of this Thesis addresses cosmic inflation, where the quantum fluctuations of the inflaton field freeze and get amplified in the expanding …

  4. Fluctuation-mediated interactions of atoms and surfaces on a mesoscopic scale

    Thermal and quantum fluctuations of the electromagnetic near field of atoms and macroscopic bodies play a key role in quantum electrodynamics (QED), as in the Lamb shift. They lead, e.g., to atomic level shifts, dispersion interactions (Van der Waals-Casimir-Polder interactions), and state …
