  1. 11. Linear response theory : from black hole thermalization to Weyl semimetals

    Författare :Jorge Laraña Aragón; Bo Sundborg; Edwin Langman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Linear response theory is an incredibly powerful calculation tool. We apply this framework in quantum field theory to a variety of models originated from distinct areas in theoretical physics and for different reasons. LÄS MER

  3. 12. Phenomenology of Inert Scalar and Supersymmetric Dark Matter

    Författare :Erik Lundström; Joakim Edsjö; Lars Bergström; Michel Tytgat; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dark matter; inert scalars; supersymmetry; indirect detection; accelerator searches; Physics; Fysik; Astroparticle physics; Astropartikelfysik; Elementary particle physics; Elementarpartikelfysik; teoretisk fysik; Theoretical Physics;

    Sammanfattning : While the dark matter has so far only revealed itself through the gravitational influence it exerts on its surroundings, there are good reasons to believe it is made up by WIMPs – a hypothetical class of heavy elementary particles not encompassed by the Standard Model of particle physics. The Inert Doublet Model constitutes a simple extension of the Standard Model Higgs sector. LÄS MER

  4. 13. Doing Physics - Doing Gender : An Exploration of Physics Students' Identity Constitution in the Context of Laboratory Work

    Författare :Anna T Danielsson; Cedric Linder; Tora Holmberg; Boel Berner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Learning; Higher Education; Science Education; Physics Education; Gender; Situated Learning; Physics; Fysik; Fysik med inriktning mot fysikens didaktik; Physics with specialization in Physics Education;

    Sammanfattning : In Sweden today women are greatly under-represented within university physics and the discipline of physics is also symbolically associated with men and masculinity. This motivates in-depth investigations of issues of physics, learning and gender. LÄS MER

  5. 14. Studies of Long-Lived Supersymmetric Top Quarks and Online Monitoring of the ATLAS First Level Calorimeter Trigger

    Författare :Marianne Johansen; Sten Hellman; David Milstead; Peter Christiansen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; fundamental questions in physics; supersymmetry; stable massive particles; LHC; the ATLAS experiment; the level-1 calorimeter trigger; CERN; Elementary particle physics; Elementarpartikelfysik; fysik; Physics;

    Sammanfattning : The Large Hadron Collider (LHC) has recently started colliding protons  at  7 TeV centre-of mass energy. Extensive searches for hitherto unobserved particles and physics processes will be made as part of an ambitious scientific programme which aims to answer some of the fundamental questions in modern physics.

  7. 15. FPGA-based Instrumentation for Advanced Physics Experiments

    Författare :Attila Hidvégi; Samuel Silverstein; Martin Grossmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Instrumentation; Data acquisition; clock distribution; trigger; FPGA; PCB; LHC; ATLAS; XFEL; fysik; Physics;

    Sammanfattning : Modern physical experiments often demand advanced instrumentation based on advances in  technology. This work describes four instrumentation physics projects that are based on modern, high-capacity Field-Programmable Gate Arrays, making use of their versatility, programmability, high bandwidth communication interfaces and signal processing capabilities.
