  1. 1. The Bloch-Messiah theorem and its application to overlaps

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Frieder Selisko; [2023]
    Keywords : Physics and Astronomy;

    Abstract : The Bogoliubov transformation is the starting point for the Hartree-Fock-Bogoliubov method and thus for many theoretical approaches that describe heavy nuclei. This transformation is based on two matrices, denoted by U and V, which are called Bogoliubov amplitudes. In this paper the properties of these matrices are investigated. READ MORE

  3. 2. Utfodring av katter i Sverige : samband mellan utfodring och övervikt respektive utfodring och problembeteenden hos katten

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Daniela Larsson; [2022]
    Keywords : torrfoder; våtfoder; fri tillgång; body condition score; BCS; hull; problembeteenden;

    Abstract : Övervikt är ett ökande problem hos våra sällskapsdjur. Att bedöma hull hos katter är precis som för andra sällskapsdjur en utmaning. Användandet av en hullbedömningsskala så som Body Condition Score (BCS) är ett värdefullt hjälpmedel för att på ett mer objektivt sätt bedöma en katts hull. READ MORE

  4. 3. On the superconducting critical temperature in Eliashberg theory

    University essay from KTH/Fysik

    Author : Max Oliveberg; [2021]
    Keywords : Eliashberg; Superconductivity; Mathematical Physics; Eliashberg; Supraledning; Matematisk Fysik;

    Abstract : This thesis presents a brief synopsis of the derivations of the BCS and Eliashberg equations. An analytic formula for the critical temperature $T_c$ in Eliashberg theory is derived, which contains a sum of iterative integral corrections. READ MORE

  5. 4. Fibre quality and fertility in male alpacas in Cusco region, Peru

    University essay from SLU/Dept. of Clinical Sciences

    Author : Fanny Bengtsson; [2016]
    Keywords : alpaca; camelid; fibre quality; fertility;

    Abstract : The aim of this study was to evaluate if there is any correlation between fibre quality and male mating behaviour (as a marker of fertility) in alpacas. The theory was that the more masculine males would have coarser fibres with a larger diameter because of higher testosterone levels. READ MORE

  6. 5. Efficient Computational Procedure for the Analytic Continuation of Eliashberg Equations

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Joakim Johansson; Fredrik Lauren; [2014]
    Keywords : superconductivity; analytic continuation; BCS theory;

    Abstract : The superconducting order parameter and the mass renormalization function can be solved either at discrete frequencies along the imaginary axis, or as a function of continuous real frequencies. The latter is done with a method called analytic continuation. READ MORE
