  2. 1. Core-hole Clock Spectroscopy Using Hard X-rays : Exciting States in Condensed Matter

    Author : Fredrik Johansson; Andreas Lindblad; Carla Puglia; Tomas Edvinsson; Marc Simon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; core-hole clock; resonant Auger; XPS; black phosphorous; TMDC; perovskite; graphene; coincidences spectroscopy; synchrotron radiation; HAXPES;

    Abstract : This thesis is about how electrons move from one place to another, that is charge transfer dynamics. Charge transfer dynamics is an important property governing chemical and physical changes that form the base for many applications such as electronics, optoelectronics and catalysis. READ MORE

  4. 2. Simulation of relaxation processes in complex condensed matter systems : Algorithmic and physical aspets

    Author : Tomas Oppelstrup; Mikhail Dzugutov; Göran Wahnström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Condensed matter physics; Kondenserade materiens fysik; Numerical analysis; Numerisk analys; Materials science; Teknisk materialvetenskap; Defects and diffusion; Defekter och diffusion;

    Abstract : This thesis summarizes interrelated simulation studies of three different physical phenomena. The three topics are: simulation of work hardening of materials using dislocation dynamics, investigation of anomalous diffusion in supercooled liquids using molecular dynamics,and kinetic Monte-Carlo simulation of annealing of radiation damaged materials.

  5. 3. A Comprehensive Experimental Approach to Multifunctional Quantum Materials and their Physical Properties : Geometry and Physics in Condensed Matter

    Author : Elisabetta Nocerino; Martin Månsson; Stephen Blundell; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum materials; neutron; muon; X-ray; symmetry; phase transitions; Material and Nano Physics; Material- och nanofysik;

    Abstract : This thesis ranges within the vast framework of experimental condensed matter physics. Several different systems, and physical phenomena, are presented here from a structuralist standpoint. READ MORE

  6. 4. Interacting Dirac Matter

    Author : Saikat Banerjee; Alexander V. Balatsky; Jens Paaske; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dirac; superconductor; magnon; interaction; Fermi liquid theory; renormalization; Fysik; Physics;

    Abstract : The discovery of graphene in 2004 has led to a surge of activities focused on the theoretical and experimental studies of materials hosting linearly dispersive quasiparticles during the last decade. Rapid expansion in the list of materials having similar properties to graphene has led to the emergence of a new class of materials known as the Dirac materials. READ MORE

  7. 5. Dark matter electron interactions in detector materials

    Author : Einar Urdshals; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; effective theory; Dark matter; direct detection;

    Abstract : Dark Matter (DM) makes up 85% of the matter content of the universe, and its gravitational effects are seen on scales ranging from that of cosmology to that of galactic astrophysics. The nature of DM is, however, unknown. READ MORE
