  1. 31. Design and engineering of light-driven dynamic films for bioelectronic interfacing

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Luca Terenzi; [2023]
    Nyckelord :Conductive polymers; Stimuli responsive materials; Azopolymers; Cell-chip coupling; Bioelectronics; Konduktiva polymerer; Stimuli-känsliga material; Azopolymerer; Cell-chip-koppling; Bioelektronik;

    Sammanfattning : In the realm of neuroelectronics, the challenge lies in achieving finer observations of physiological processes to comprehend neuronal interactions and computations. This necessitates the development of more compliant and biomimetic interfaces for improved integration with biological tissues, enabling finer physiological process observations. LÄS MER

  3. 32. Investigation of a newrepresentation of spin

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Minna Palmgren Thun; [2023]
    Nyckelord :Material theory; Spin; Statistical physics; Second quantization; Materialteori; spinn;

    Sammanfattning : The Bose-Hubbard Model, a tight binding model within solid state theory can be solved exactly using a number theoretical approach. From this approach, in the two sited Bose-Hubbard model, the hopping term in the model takes the form of a Pauli x matrix. The hopping term can be interpreted as a two energy level system or a dimer with k+1 particles. LÄS MER

  4. 33. Improving polarizing neutron optics by introducing 11B4C as interlayers

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Martin Falk; [2023]
    Nyckelord :Thin film multilayers; Neutron optics; Neutron polarization;

    Sammanfattning : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. LÄS MER

  5. 34. Spin Representations, Clifford Algebras and Spinors

    Kandidat-uppsats, Uppsala universitet/Matematiska institutionen

    Författare :Simon Wogel; [2023]
    Nyckelord :Algebras; Clifford algebras; Spinors; Representations; Lie algebras; Lie groups; Algebror; Cliffordalgebror; Spinorer; Representationer; Liealgebror; Liegrupper;

    Sammanfattning : We begin by giving some theoretical background to the underlying concepts of spin representations and spinors. This is done from the perspective of Lie groups and Lie algebras. In particular, we discuss the functionality of Clifford algebras in the determination of the double-covering spin groups. LÄS MER

  7. 35. Spinning Gold: Unraveling the Secrets of Value Creation from Spin-offs

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för marknadsföring och strategi

    Författare :Andreas Groth; Fabian Bevanda; [2023]
    Nyckelord :Spin-Offs; Corporate Focus Hypothesis; Optimal Leverage Hypothesis;

    Sammanfattning : This thesis explores the dynamics of value creation in American corporate spin-offs between 1995-2019 from the dual perspectives of the corporate focus and optimal leverage hypotheses. The research employs a comprehensive dataset of 164 cases, examining the impacts of spin-offs on long-term abnormal stock returns and both unadjusted and industry-adjusted operating performance.
