1. Quantum mechanical modelling and electrochemical stability of sodium based glassy electrolyte for all-solid-state batteries
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Increasing energy demand draws attention to new materials for improving current energy storage technologies. Particular interest is directed at solid state batteries and glass Na3ClO electrolyte is a promising candidate. LÄS MER
2. Gossiping electrons : Strong decoherence from screening
Kandidat-uppsats, Uppsala universitet/MaterialteoriSammanfattning : In a strongly correlated material the localized electrons, typically the electrons in the 3d-orbitals, become entangled with each other through the Coulomb interaction. However, these electrons also interact with more mobile (itinerant) electrons in the s- and p-orbitals. LÄS MER
3. First principles DFT study of polyethylene insulation containing chemical impurities - implementing counterpoise correction
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Density functional theory (DFT) calculations of polyethylene (PE) HVDC cable insulation have been performed for systems containing four different chemical impurities: acetophenone, cumene, $\alpha$-methyl styrene and $\alpha$-cumyl alcohol. Systems were generated by molecular dynamics (MD) equilibration at four different temperatures relevant for cable insulation applications: 277 K, 293 K, 343 K and 363 K. LÄS MER
4. A Platform for a Wheeler's Delayed-Choice Experiment in Optical Fiber
Master-uppsats, Linköpings universitet/InformationskodningSammanfattning : Quantum mechanics has played a big role in the development of our understanding of the smallest things in the universe. It has provided descriptions for phenomena like single electrons or single photons, which are single particles of light. One of the most mysterious properties of quantum systems is the ability to behave as a particle or a wave. LÄS MER
5. Klassisk–kvantmekanisk tidsalternerande metod för simulering av strålningsinducerade defekter i metaller
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : Strålskador i metalliska komponenter är oundvikligt för metaller i reaktormiljöer. Den viktigaste materialparametern för beräkningar av strålningsinducerad defektbildning är tröskelenergin för defektbildning, som ofta bestäms genom molekyldynamiksimuleringar (MD) baserade på den empiriska metoden EAM, och nyligen även den kvantmekaniska metoden täthetsfunktionalteori (DFT).
