  1. 1. Fractal superconducting resonators for the interrogation of two-level systems

    Författare :Sebastian Erik de Graaf; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cooper-pair box; decoherence; electron spin resonance; two-level systems; atomic force microscopy; quasiparticles; near-field scanning microwave microscopy; Superconducting resonators; circuit quantum electrodynamics;

    Sammanfattning : In this thesis we use high-Q superconducting thin-film microwave resonators to interact with several types of quantum mechanical two-level systems. Such a resonator is used as the central building block in a cryogenic near-field scanning microwave microscope (NSMM) to reach a completely new regime of NSMM operation. LÄS MER

  2. 2. Étude comparative des approches créatrices et technologiques au Groupe de Recherches Musicales à Paris et à l’Elektronmusikstudion à Stockholm 1965-1980 : Deux directions artistiques différentes à partir d’une idée commune

    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Pierre Schaeffer; Knut Wiggen; Groupe de Recherches Musicales; Elektronmusikstudion; Lasse Thoresen; Aural Sonology; electroacoustic music; acousmatic music; music concrète; text-sound; tripartition; poietic level; neutral level; typo-morphology; Gestalt; Pierre Schaeffer; Knut Wiggen; Groupe de Recherches Musicales; Elektronmusikstudion; Lasse Thoresen; Aural Sonology; musique électroacoustique; musique acousmatique; musique concrète; tripartition; text-sound; niveau poïétique; niveau neutre; typo-morphologie; Gestalt; Musicology; musikvetenskap;

    Sammanfattning : La thèse en question trace un parcours comparatif sur les approches créatrices et technologiques qui ont été développées au GRM (Groupe de Recherches Musicales) et à l’EMS (Elektronmusikstudion) de 1965 à 1980. Cette recherche vise à étudier les interactions principales entre les concepts musicaux des pionniers des musiques électroacoustiques en France et en Suède, Pierre Schaeffer et Knut Wiggen et l’évolution des directions artistiques au sein de leur institutions.

  3. 3. Innovation under pressure : Reclaiming the micro-level exploration space

    Författare :Katarina Lund Stetler; Mats Magnusson; Jens Hemphälä; Salomo Sören; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Ambidexterity; exploration; exploitation; creativity; innovation; micro-level exploration space; operational level; operations; operational effectiveness; employee; lean; lean thinking; process management; streamlining; flow; Machine Design; Maskinkonstruktion;

    Sammanfattning : Research & Development (R&D) departments are becoming increasingly structured and routine-based, with tight schedules and daily follow-ups. This way of working stems from increased demands for delivering products to customers quickly and with high quality at a low price. LÄS MER

  4. 4. Maximal Unitarity at Two Loops : A New Method for Computing Two-Loop Scattering Amplitudes

    Författare :Kasper J. Larsen; Lisa Freyhult; David Kosower; Joseph Minahan; Paul Heslop; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Amplitudes; NNLO calculations; Quantum Chromodynamics; Unitarity; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : The study of scattering amplitudes beyond one loop is necessary for precision phenomenology for the Large Hadron Collider and may also provide deeper insights into the theoretical foundations of quantum field theory. In this thesis we develop a new method for computing two-loop amplitudes, based on unitarity rather than Feynman diagrams. LÄS MER

  5. 5. Exilens dilemma: att stanna eller att återvända : Beslut i Sverige av polska kvinnor som överlevde KZ-lägret Ravensbrück och räddades till Sverige 1945-1947

    Sammanfattning : This thesis is about the intersection of great narratives and individual decisions. In the intersection, the dilemma of exile is discussed: to remain in exile or return to one’s homeland. LÄS MER
