  1. 1. Plasmons in Nanostructured Graphene

    Författare :Tobias Wenger; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; linear response theory; surface plasmon-polaritons; Plasmons; surface electrodynamics; plasmonics; graphene; random phase approximation;

    Sammanfattning : Plasmons, collective electron density oscillations, provide physicists with intriguing challenges and possibilities. The inherent many-body properties of the plasmons together with their ability to localize light into small volumes make the plasmons interesting from both a purely theoretical viewpoint and an applications point of view.

  3. 2. Graphene plasmons in nanostructured environments

    Författare :Tobias Wenger; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nonlocal response; Graphene plasmons; subwavelength electromagnetic scattering; linear response Green s functions;

    Sammanfattning : This thesis explores the combination of electromagnetism with electrons in graphene. Graphene is a one atom thick layer of carbon atoms which contains electrons that exhibit rather special properties in terms of their conduction abilities. LÄS MER

  4. 3. Plasma Oscillations in Holographic Quantum Matter

    Författare :Marcus Tornsö; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; holography; quasinormal modes; gauge gravity duality; graphene; strong coupling; plasmonics; strongly correlated media;

    Sammanfattning : In this thesis we explore strongly correlated matter in the framework of holographic duality. Specifically, we examine the quasinormal modes of such systems, and we extend the current framework to efficiently and naturally cover plasmons and other collective modes that may be found within strongly correlated matter.
