  1. 1. Computational modelling of photosynthetic excitons coupled to a microcavity

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Ilmari Turunen; [2022]
    Nyckelord :Cavity QED; LH2; Chlorophyll; Exciton; Polariton; Transition dipole moment; Absorbance; Physics and Astronomy; Chemistry; Biology and Life Sciences;

    Sammanfattning : Cavity quantum electrodynamics (QED) is a theory that is used for describing the interaction between matter and cavity modes. Not until relatively recently, cavity QED has been extended to the study of photosynthetic light-harvesting complexes (LHCs). LÄS MER

  3. 2. Reaction of Copper and Copper(I) Iodide with Iodine and Strong Field Ligands

    Master-uppsats, KTH/Tillämpad fysikalisk kemi

    Författare :Aya Ali; [2022]
    Nyckelord :in films; AFM; copper iodide; solar cells; transparent conductive films; tunnfilm; AFM; koppar jodid; solceller; transparent ledande film;

    Sammanfattning : Perovskit solceller (PSCs) är kända som 'ljusomvandling' enheter med ökad omvandlingseffektivitiet (PCE). PSCs är kända för detta flexibilitet och hög tolerans mot defekter och består av fem lager med olika material och egenskaper. LÄS MER

  4. 3. Study of the vibronic mixing in chlorophylls with multidimensional spectroscopy

    L3-uppsats, Lunds universitet/Kemiska institutionen

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

    Sammanfattning : 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). LÄS MER

  5. 4. Decoherence-assisted transport in pigment protein complexes

    Kandidat-uppsats, Uppsala universitet/Teoretisk kemi

    Författare :Adrià Sonet Ventosa; [2014]
    Nyckelord :Entanglement; concurrence; nonlocality; electronic energy transfer; FMO complex; light-harvesting complex.;

    Sammanfattning : Two chlorophylls of the FMO complex, the light-harvesting complex of the green sulfur bacteria, are modeled as two coupled qubits, each surrounded by one spin-bath simulating the environment. The dynamics of the system at a non-zero temperature provide exact analytical expressions for the transition probability and the coherence. LÄS MER

  7. 5. Structural and functional analysis of violaxanthin de-epoxidase

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Kuo Guo; [2013]
    Nyckelord :Proteinvetenskap; Protein Science; Chemistry;

    Sammanfattning : Non photochemical quenching (NPQ) is an important way for plants to protect themselves from photooxidative damage. In higher plants, the major and most rapid part of NPQ is qE, which is controlled by the Violaxanthin de-epoxidase (VDE) and zeaxanthin epoxidase (ZE). VDE converts Violaxanthin (Vx) to Antheraxanthin (Ax), and then to Zeaxanthin (Zx). LÄS MER
