2. Charge transport in a Hubbard-Holstein junction: Preliminary results from a DFT approach.
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : Many-body systems are extremely complicated to describe due to mutual interactions between the constituent particles. This is for example the case of systems with electron-electron (e-e) and electron-phonon (e-ph) interactions. READ MORE

3. Density Functional Theory for the Hubbard-Holstein model
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : The physics of interacting many-body systems is a very complex and challenging subject. Therefore one in general needs to use simplified models and approximate methods for studying these systems theoretically. READ MORE

4. Basic quantisation rules of semiclassical analysis
University essay from Uppsala universitet/Analys och sannolikhetsteoriAbstract : Semiclassical analysis is the study of how to connect classical mechanics with quantummechanics in a mathematically rigorous way. What is crucial for quantum mechanics isthat the operators that occur are self-adjoint and map a subset of L2 into L2. This hasbeen proven in this thesis. READ MORE

5. Orbital-free Density-Functional Theory in a Finite Element Basis
University essay from Linköpings universitet/Teoretisk FysikAbstract : In this work, we have implemented an orbital-free density functional theory (OF-DFT) solver using the finite element method. In OF-DFT, the total ground state energy is minimized directly with respect to the electron density, rather than via orbitals like in the standard Kohn-Sham approach. READ MORE
