1. The Collapse of Decoherence : Can Decoherence Theory Solve The Problems of Measurement?
University essay from Uppsala universitet/MaterialteoriAbstract : In this review study, we ask ourselves if decoherence theory can solve the problems of measurement in quantum mechanics. After an introduction to decoherence theory, we present the problem of preferred basis, the problem of non-observability of interference and the problem of definite outcomes. READ MORE

2. The black hole information paradox and holography
University essay from Uppsala universitet/Teoretisk fysikAbstract : Hawking theorized in 1974 that black holes emit particles as a quantum effect. It follows from this fact that a black hole that emits particles while absorbing none ends up evaporating. The process of black hole evaporation studied from semiclassical gravity violates quantum mechanics leading to serious problems. READ MORE

3. On quantum systems and the measurement problem
University essay from Stockholms universitet/FysikumAbstract : We focus on the Tensor Product Structure (TPS) of the Hilbert space and the fact that a choice in the TPS has an impact on the representation of the studied quantum system. We define the measurement problem in quantum mechanics and present some theories about quantum mechanics, each of them highlighting a different approach to quantum measurements. READ MORE

4. Supersymmetry in Quantum Mechanics
University essay from Uppsala universitet/Institutionen för materialvetenskapAbstract : The introduction of supersymmetry has led to great progress in the study of quantum field theories. Notably, with supersymmetry, properties of a quantum field theory can be computed with higher precision than what would otherwise be possible. In this project, we investigate supersymmetry in the context of quantum mechanics. READ MORE

5. Numerical Simulations of Resonant Tunnelling Diodes
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN).
