  1. 1. Z2-Gauge Theory with Matter : Dispersive behaviour of a dimer in a 1+1-dimensional lattice

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Filip Ekblom; [2023]
    Keywords : Spin chain; Ising model; Dimer; Lattice; Lattice gauge theory;

    Abstract : The intention with this thesis is to investigate a dimer in a spin chain. Inorder to do that, a model from Z2-gauge theory is taken as the theoretical motivation to construct a discrete lattice with Ising spin properties. A dimer is then allowed to exist indirectly in the empty space between sites. READ MORE

  3. 2. Ligand-stimulated cleavage of PDGFR-beta

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Agni Karolina Tsiatsiou; [2023]
    Keywords : ;

    Abstract : Platelet-derived growth factor receptors (α and β) are included in the family of receptor tyrosine kinases (RTKs). The dimeric PDGF ligands bind to the PDGF receptors and this results in receptor dimerization, autophosphorylation, and thus activation. The autophosphorylated receptor dimer activates numerous signaling pathways. READ MORE

  4. 3. Co-evolutional anaylsis of the Na+,K+-ATPase’s β-subunit dimerization

    University essay from KTH/Tillämpad fysik

    Author : Sebastian Bauer; [2023]
    Keywords : Na ; K -ATPase NKA ; Co-evolution; Dimerization; Direct coupling analysis DCA ; Molecular dynamic MD simulation; Contact filtering; Mapping; Na ; K -ATPas NKA ; Samevolution; Dimerisering; Direkt kopplingsanalys DKA ; Molekylär dynamisk MD simulering; Kontaktfiltrering; Kartläggning;

    Abstract : Does the active membrane transporter, Na+,K+-ATPase dimerize? If it does, whatis the functional benefit? Does it increase or decrease the turnover rate? Theseare still unanswered questions and current research topics. Previous studies havedemonstrated dimerizations in closely related proteins of the P-type ATPase family. READ MORE

  5. 4. Numerical simulations of ultrafast dynamics in plasmonic nanostructures

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nils Henriksson; [2023]
    Keywords : Ultrafast nanophotonics; Three temperature model; Numerical simulations;

    Abstract : Plasmonic effects in nanosized particles enhance the interaction between light and matter due to the localized surface plasmon resonance, with potential applications such as all-optical transistors and optical computers. Commonly, the dynamics of nanoparticles’ optical properties are assessed via pump-probe spectroscopy, where a plasmonic structure is exited by an initial laser, the pump. READ MORE

  6. 5. Investigation of a newrepresentation of spin

    University essay from Uppsala universitet/Materialteori

    Author : Minna Palmgren Thun; [2023]
    Keywords : Material theory; Spin; Statistical physics; Second quantization; Materialteori; spinn;

    Abstract : The Bose-Hubbard Model, a tight binding model within solid state theory can be solved exactly using a number theoretical approach. From this approach, in the two sited Bose-Hubbard model, the hopping term in the model takes the form of a Pauli x matrix. The hopping term can be interpreted as a two energy level system or a dimer with k+1 particles. READ MORE
