  1. 1. WIMP searches in an Effective Field Theory Framework from XENON1T to XENONnT

    Författare :Vasile Cristian Antochi; Conrad Jan; Alfredo Davide Ferella; Samuel Silverstein; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WIMP; Dark Matter; EFT; Chiral EFT; Direct Detection; PMT testing; fysik; Physics;

    Sammanfattning : Observations from cosmology and astronomy suggest that most of the matter in the Universe is comprised of dark matter. In this thesis the evidence for dark matter and the possible candidates are explored, focusing on the Weakly Interacting Massive Particles (WIMPs) hypothesis. LÄS MER

  3. 2. From Quantum to Classical Scattering of Kerr Black Holes : A construction of massive higher-spin scattering amplitudes and their classical limits

    Författare :Lucile Cangemi; Henrik Johansson; Yu-tin Huang; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Higher-spin theory; higher-spin amplitudes; Kerr black holes; EFT; black hole scattering; classical limit; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : Gravitational scattering processes involving black holes as asymptotic states can provide insight into the classical dynamics of binary black hole systems. The observed gravitational waves emitted during mergers need to be compared to high-precision theoretical predictions. LÄS MER

  4. 3. The data perspective on chiral effective field theory

    Författare :Boris Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chiral EFT; few-nucleon physics; uncertainty quantification; two-nucleon scattering; nuclear physics;

    Sammanfattning : The scientific method implies a dynamical relationship between experiment and theory. Indeed, experimental results are understood through theories, which themselves are of less value until confronted with experiment. LÄS MER

  5. 4. Extended Förster Theory of Electronic Energy Transport within Pairs of Reorienting Chromophoric Molecules

    Författare :Nils Norlin; Lennart B.-Å. Johansson; Yehudi K. Levine; Umeå universitet; []
    Nyckelord :electronic energy migration transfer; extended Förster theory; orientation factor; DDEM; PDDEM; time-resolved fluorescence anisotropy; time-correlated single photon counting; Brownian dynamics; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : An extended Förster theory (EFT), previously derived (L. B.-Å. Johansson et al. LÄS MER

  7. 5. On the quantitative analysis of electronic energy transfer/migration in proteins studied by fluorescence spectroscopy

    Författare :Mikael Isaksson; Lennart Johansson; Bo Albinsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysical Chemistry; Biophysical chemistry; Biofysikalisk kemi;

    Sammanfattning : Two recently developed theories of electronic energy transfer/migration were for the first time applied to real protein systems for extracting molecular distances. The partial donor-donor energy migration (PDDEM) is an extension to the previously developed donor-donor energy migration (DDEM, F Bergström et al PNAS 96, 1999, 12477) which allows using chemically identical but photophysically different fluorophores in energy migration experiments.
