1. A C++ Matrix library for computing the Gateaux derivative of the Fermi-Dirac operator
Kandidat-uppsats, Uppsala universitet/Avdelningen för beräkningsvetenskapSammanfattning : Computing the Fermi-Dirac operator is done through recursive polynomial expansions, using the SP2 and SP2 Acc algorithms. The Gateaux derivative is computed for both schemes by mapping the zeroth and first order matrices onto a block upper triangular matrix, which is implemented in Python using Numpy arrays to store full matrices and in C++ by first constructing a basic matrix library to use as blocks in a later created block upper triangular matrix library which only directly references two blocks in a 2 x 2 block matrix.

2. Error propagation in nuclear models
Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenSammanfattning : In this thesis we perform error analysis of a nuclear model based on density-functional theory developed in Lund. The Lund model allows us to perform calculations of nuclear spectra more efficiently by constructing a simple effective Hamiltonian reproducing the quadrupole deformation and pairing interaction strength parameters of a spherical Hartree-Fock reference functional.

3. The Bloch-Messiah theorem and its application to overlaps
Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenSammanfattning : 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. LÄS MER

5. Konfetti i hela min säng. En studie av prisnominerade skönlitterära debutanter 2010–2020
Magister-uppsats, Göteborgs universitet/Institutionen för litteratur, idéhistoria och religionSammanfattning : This master’s thesis aims to investigate how literary prize nominated first-time fiction writers experience the circumstances around publishing their debut work, with particular focus on the significance of literary awards. The study is based on semi-structured interviews with ten debut authors from the 2010’s: Tomas Bannerhed, Anna Fock, Tove Folkesson, Carolina Fredriksson, Marit Kapla, Agnes Lidbeck, Sami Said, Karin Smirnoff, Stina Stoor, Isabelle Ståhl.
