  1. 1. Localized and extended states in finite-sized mosaic Wannier-Stark lattices

    University essay from KTH/Tillämpad fysik

    Author : Emrah Tortumlu; [2023]
    Keywords : Applied Physics; Condensed matter physics; quantum technology; quantum nanophotonics; localization; mobility edge; phase transition; Tillämpad Fysik; Kondenserade materiens fysik; kvantteknologi; kvantnanofotonik; lokalisering; fasövergång;

    Abstract : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

  3. 2. Synthesis and characterization of novel hybrid organic-inorganic materials

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Emil Blomdahl; [2021]
    Keywords : Hybrid organic-inorganic material; perovskite; X-Ray diffraction; thermal gravimetric analysis; differential scanning calorimetry; Hybrida organiska-ooorganiska material; perovskit; röntgendiffraktion; thermal gravimetric analysis; differential scanning calorimetry;

    Abstract : Efterfrågan på bättre och mer hållbart material ökar. Mer effektivt material kommer att behövas för att möta den ökande, globala efterfrågan. READ MORE

  4. 3. Searching for signatures of compositeness of the Higgs boson

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Mårten Bertenstam; [2021]
    Keywords : two-Higgs-doublet model; composite Higgs model; composite two-Higgs-doublet model; phase transition; cosmological phase transition; electroweak phase transition; gravitational waves; gravitational wave background; Physics and Astronomy;

    Abstract : In this master thesis we consider some phenomenological aspects of two-Higgs-doublet models, both elementary and composite ones. The emphasis is on calculating and understanding first order phase transitions in such models, constrained to be in agreement with existing collider data on the Higgs sector. READ MORE

  5. 4. Development of corrosion resistant coatings using natural biopolymer and pollen

    University essay from KTH/Materialvetenskap

    Author : Alessandro Armani; [2020]
    Keywords : ;

    Abstract : Corrosion is a mechanism that highly reduces the lifetime of metals in different environments, especially in water or moisture environment. The worldwide maintenance cost due to corrosion is estimated in billions of dollars per year, and actual solutions in terms of coating usually contains toxic or environmentally harmful species.

  6. 5. Nonequilibrium gauge field in Two Particle Irreducible real time formalism

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Rasmus Hansen; [2019]
    Keywords : Gauge field; non-equilibrium; quantum field theory; Physics and Astronomy;

    Abstract : The purpose of this thesis is to study what effect a photon field has on the equations of motion and the decay of a charged scalar field in thermal equilibrium at finite temperature and outside of thermal equilibrium. To do this we calculate the two-particle irreducible effective action for the mean fields and propagators and derive their equations of motion. READ MORE
