  1. 1. Strong Light-Matter Coupling: the Road from Conventional to Cavity-Free Polaritons

    Författare :Adriana Canales Ramos; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fabry-Pérot microcavities; self-hybridized polaritons; Mie modes; Strong and ultrastrong coupling; Lorentz resonances; decay rates; cavity-free polaritons; Casimir force; 2D–crystals; plasmons; water droplets.; self-assembled microcavities;

    Sammanfattning : The interaction between light and matter is fundamental in perceiving and understanding the world. The interaction is typically weak, meaning light only perturbs matter without changing its properties. LÄS MER

  3. 2. The growth of waves by wind as a problem in nonequilibrium statistical mechanics

    Författare :Anthony Bonfils; John Wettlaufer; Kristian Gustafsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; out-of-equilibrium system; fluctuation spectrum; oscillatory force; classical Casimir effect; non-linear waves; wave turbulence; wind-wave coupling.; teoretisk fysik; Theoretical Physics;

    Sammanfattning : In 1948, Casimir predicted a net attractive force between two perfectly conducting parallel plates due to electromagnetic vacuum fluctuations. By analogy, the interaction of two ships on a wavy sea has been named Maritime Casimir effect. This is an example of force generation in non-equilibrium systems. LÄS MER

  4. 3. Van der Waals and Casimir interactions near metal films

    Författare :Mathias Boström; G. D. Mahan; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis deals with van der Waals and Casimir forces near metal films. Thick, thin and strictly two-dimensional metal films will be investigated. For many applications one can model a double quantum-well structure with two strictly two-dimensional metallic sheets. LÄS MER

  5. 4. A study of finite-size, non-perturbative and anisotropic effects on the Lifshitz-van der Waals forces and torque with material dielectric responses from first-principles calculations

    Författare :Priyadarshini Thiyam; Clas Persson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lifshitz-van der Waals forces; Casimir torque; optical calculations with density functional theory; phosphorus; phosphorene;

    Sammanfattning : The van der Waals and the Casimir-Lifshitz forces are forces of attraction that exist between neutral polarizable bodies due to quantum fluctuations. They can be repulsive depending on the material properties and the geometry of the system. LÄS MER

  7. 5. A study of finite-size and non-perturbative effects on the van der Waals and the Casimir-Polder forces

    Författare :Thiyam Priyadarshini; Clas Persson; Mathias Boström; Thomas Ederth; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; finite-size effects; non-perturbative theory; van der Waals and Casimir Polder forces; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : This licentiate thesis addresses two important aspects of the van der Waals and the Casimir-Polder ground-state and excited-state (resonance) interactions between two atoms or molecules. The first is the finite-size effect and the second is the non-perturbative effect. LÄS MER
