1. Finite element density functional description of linear molecules
University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Abstract : This report describes a project performed at Linnaeus University with the task of solving the Schrodinger equation for electrons in homonuclear diatomic molecules, using the finite element method in Python. The Schrodinger equation is solved for the hydrogen atom, nitrogen atom, hydrogen molecule and nitrogen molecule using a finite element method. READ MORE

2. Misalignment effects on the physics performance of the inner tracker upgrade at the ALICE experiment
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikAbstract : This thesis deals with the physics performance of an approved inner tracker upgrade of the ALICE experiment involving a novel and ultra-thin silicon detector with a cylindrical geometry. During the thesis work, a method was developed in simulations to induce distortions to the detector’s geometry, and the resulting loss in physics performance was evaluated. READ MORE

3. Designing a reactive feedback feature for end-users in web-based media software
University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronikAbstract : Customer feedback is essential for improving a company's products or services and increasing customer satisfaction. Despite its value, user involvement faces many challenges, such as low user motivation and feedback with missing context information. READ MORE

4. Simulation-based discrimination of Crab pulsar models with XL-Calibur
University essay from KTH/FysikAbstract : Polarisation of X-ray light is being investigated with polarimeters to extend the borders of what can be observed. Distant compact objects, such as pulsars, that are to small on the sky to be analysed with imaging can be investigated by analysing the polarisation of the emitted light. This can reveal physics previously hidden by their small nature. READ MORE

5. Gravitational Collapse of a Massless Scalar Field in a Theory of Minimally Modified Gravity
University essay from KTH/FysikAbstract : This thesis explores the spherically symmetric gravitational collapse of a massless scalar field in a minimally modified gravity theory denoted VCDM (V replaces $\Lambda$ in the $\Lambda$CDM abbreviation), a class of theories propagating the same degrees of freedom as general relativity at the expense of broken 4D diffeomorphism invariance. Numerical evolution of the equations of motion reveals that for small initial scalar profile amplitudes, no black hole forms from the collapse. READ MORE
