1. A C++ Matrix library for computing the Gateaux derivative of the Fermi-Dirac operator
University essay from Uppsala universitet/Avdelningen för beräkningsvetenskapAbstract : 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. Transverse Momentum Spectra in pp collisions (\sqrt{s}\) = 7 TeV and \(\sqrt{s}\) = 13 TeV in ALICE
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikAbstract : In this project particle production as a function of transverse momentum (\(p_{\rm T}\)) in proton-proton collisions at a center-of-mass energy (\(\sqrt{s}\)) of 7 TeV and 13 TeV has been studied. The transverse momentum is interesting to study since it reflects momentum created in the collision (before the collision, all momentum is in the beam - going in a longitudinal direction) and therefore gives information on the collision dynamics.

3. Quantum Transport in Topological Insulator Nanowires
University essay from KTH/FysikAbstract : Three-dimensional topological insulators are materials that have a bulk band gap like a traditional insulator, but which hold topologically protected conducting surface states. In this thesis we present a numerical analysis of the surface states of topological insulator nanowires in the tight-binding approximation. READ MORE

4. How to Rise from Ashes : A Comprehensive Guide to Finally Understand Canonical Quantization and Build Quantum Mechanics from Scratch
University essay from Uppsala universitet/Materialteori; Uppsala universitet/Avdelningen för teoretisk filosofiAbstract : In this review essay, we account for the historical development of canonical quantization. By a detailed review of The Ultraviolet Catastrophe, The Photoelectric Effect, Compton Scattering, Matter Waves and Bohr's Atomic Model we learn about Old Quantum Theory. READ MORE

5. Review of Black-hole Amplitudes
University essay from Uppsala universitet/Teoretisk fysikAbstract : Abstract: In this review, we referred to several recent works about the black-hole amplitudes. By regarding the black holes as elementary particles, we wrote down the amplitudeswhich describe the black-hole graviton scattering. READ MORE
