  1. 21. Study of the vibronic mixing in chlorophylls with multidimensional spectroscopy

    University essay from Lunds universitet/Kemiska institutionen

    Author : Ignacio Martínez Casasús; [2021]
    Keywords : Two-dimensional spectroscopy; Ultrafast spectroscopy; Chlorophyll a; Chlorophylls; Photosynthesis; Light harvesting; Vibronic mixing; Quantum coherence; Chemical physics; Chemistry;

    Abstract : Chlorophylls comprise one of the most important families of molecules for the photosynthetic process. Chlorophyll-like molecules have been classically interpreted under the Gouterman model, being thought to feature two independent transitions, Qy(S1) and Qx(S2). READ MORE

    Abstract : Synchrotron and Free Electron Laser (FEL) light is becoming an increasingly sought after tool for almost all scientific research aspects. MAX IV Laboratory introduced the first 4th generation light source that provides the brightest synchrotron light in the world. READ MORE

  4. 23. Monte-Carlo simulations of an AmBe neutron source

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Josefine Sjöberg; [2021]
    Keywords : Serpent; neutron; gamma; radiation dose; AmBe source; polyethylene;

    Abstract : The Department of Physics and Astronomy in Uppsala is planning to construct a source-based neutron irradiation facility at Ångströms laboratory. The purpose of this facility will, as of now, mainly be for students and employees to conduct scientific experiments and to calibrate the university's neutron scintillator detectors. READ MORE

  5. 24. Seeing Stars - Intensity Interferometry in the Laboratory and on the Ground

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Colin Carlile; [2021]
    Keywords : Stellar Physics Instrumentation Interferometry Cherenkov Telescope Array Intensity Interferometry; Physics and Astronomy;

    Abstract : Context Since the time of Tycho Brahe astronomy has been an observing science defined by the quality of its instrumentation. The introduction of primitive telescopes by Galileo in 1609 began a period of development of ever-larger telescopes with greater measuring precision. READ MORE

  6. 25. Čerenkov emission of whistler waves by electron holes

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Nedjma Ouahioune; [2021]
    Keywords : Čerenkov; Whistler waves; Resonance; Electron holes; Plasma; Physics; Space Physics; Astronomy; Plasma waves; Instabilities; Čerenkov; visslarvågor; elektromagnetiska vågor; resonans; electron holes; plasma fysisk; rymdfysisk; astronomi; plasma vågor; instabilitet;

    Abstract : Electron holes are positively charged nonlinear structures in which trapped electrons are supported by a positive electrostatic potential. These structure are regularly observed in space and laboratory plasmas by means of diverging bipolar electric field signatures. READ MORE
