  1. 1. 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

  2. 2. 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

  3. 3. Effects of disorder in metallic systems from First-Principles calculations

    Author : Christian Asker; Igor Abrikosov; Jörg Neugebauer; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Iron; Nickel; Magnesium; Manganese; Molybdenum; Zirconium; Elastic Constants; High pressure; Earth s core; Density-functional theory; Ab-initio; First-Principles; Core-level shifts; Molecular Dynamics; Phonons; Dynamical Instability; Condensed matter physics; Kondenserade materiens fysik; Computational physics; Beräkningsfysik;

    Abstract : In this thesis, quantum-mechanical calculations within density-functional theory on metallic systems are presented. The overarching goal has been to investigate effects of disorder. In particular, one of the properties investigated is the bindingenergy shifts for core electrons in binary alloys using different theoretical methods. READ MORE

  4. 4. Unveiling the nature of dark matter with direct detection experiments

    Author : Vanessa Zema; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NaI; phenomenology; annual-modulation; direct-detection; cryogenics; COSINUS; polarised-nuclei; CRESST; dark-matter; phonons;

    Abstract : The desire of discovery is an anthropic need which characterises and connects the human being over the eras. In particular, observing the sky is an instinctive drive exerted by the curiosity of the mysteries which it retains. READ MORE

  5. 5. Phase transitions in novel superfluids and systems with correlated disorder

    Author : Hannes Meier; Mats Wallin; Asle Sudbø; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; condensed matter physics; phase transitions; critical phenomena; spin models; quantum phase transitions; quantum fluids; superfluidity; superconductivity; disordered systems; Bose glass; dirty bosons; vortex pinning; statistical mechanics; Monte Carlo simulation; Wolff algorithm; classical worm algorithm; Wang-Landau algorithm; Fysik; Physics;

    Abstract : Condensed matter systems undergoing phase transitions rarely allow exact solutions. The presence of disorder renders the situation  even worse but collective Monte Carlo methods and parallel algorithms allow numerical descriptions. READ MORE
