  2. 1. ON THE COUPLING OF THE LOCALIZED PLASMON AND INTERBAND TRANSITIONS IN NICKEL NANOANTENNAS

    Author : Zhaleh Pirzadeh Irannezhad; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Localized surface plasmon resonance; interband transition; nanoantenna; nickel nanoplasmonic; coupling;

    Abstract : Interaction of light with metallic nanostructures smaller than the wavelength leads to excitation of collective oscillations of “free” conduction electrons. This effect leads to locally enhanced electric fields inside and outside the nanoparticle and is called localized surface plasmon resonance (LSPR). READ MORE

  4. 2. Interactions Between Localized Surface Plasmons and Molecular Resonances

    Author : Gülis Zengin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; single particles; J-aggregates; Rhodamine 6G; Localized surface plasmon resonance; strong coupling; surface-enhanced absorption;

    Abstract : Molecular plasmonics is the study of interactions between plasmonic nanostructures and molecules. It has been basis for fundamental understanding of light-matter interactions and development of many technological applications, such as biological and chemical sensing, plasmon-enhanced spectroscopies, optical switches, and plasmon-enhanced energy harvesting.

  5. 3. Proton transfer across and along biological membranes

    Author : Johan Berg; Peter Brzezinski; Artur Osyczka; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biological membranes; cardiolipin; cytochrome bo3; cytochrome c oxidase; energy conversion; fluorescence correlation spectroscopy FCS ; localized coupling; mitochondria; proton transfer; Rcf1; respiration; single-enzyme measurement; Biochemistry; biokemi;

    Abstract : Proton-transfer reactions belong to the most prevalent reactions in the biosphere and make life on Earth possible, as they are central to energy conversion. In most known organisms, protons are translocated from one side of a membrane to the other, which generates an electrochemical gradient that drives ATP synthesis. READ MORE

  6. 4. Investigations of Strong Light-Matter Interactions in Nanophotonic Systems

    Author : Michael Stührenberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoluminescence; strong coupling; localized surface plasmon resonance; bipyramids;

    Abstract : Noble metal nanoparticles can support localized surface plasmon resonances (LSPR), thus behaving as open optical resonators. Outstanding optical properties as well as a subwavelength mode volume make plasmonic nanoparticles a promising platform for enhanced light-matter interactions. READ MORE

  7. 5. Coherent Plasmon-Plasmon and Plasmon-Exciton Interactions at the Nanoscale

    Author : Martin Wersäll; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; directional emission; coherent interactions; strong coupling; localized surface plasmon resonances;

    Abstract : Noble metallic nanoparticles which supports localized surface plasmon resonances, offers a variety of potential scientific as well as industrial applications. Due to a remarkable ability to confine light at nanoscale dimensions, far below the optical diffraction limit, together with an ability to detect minute changes in the local environment plasmonic nanoparticles have paved routes towards several new and intriguing techniques, promising for future applications in areas such as molecular sensing and quantum optics.
