1. Fano Resonances in Time-Dependent Wells
University essay from Uppsala universitet/MaterialteoriAbstract : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. READ MORE

2. Embedded eigenvalues for asymptotically periodic ODE Systems
University essay from Lunds universitet/Matematik LTHAbstract : In this thesis we investigate the persistance of embedded eigenvalues under perturbations of a certain self-adjoint Schrödinger-type differential operator in L^2(\mathbb{R},\mathbb{R}^n), with an asymptotically periodic potential. The studied perturbations are small and belong to a certain Banach space with a specified decay rate, in particular, a weighted space of continuous matrix valued functions. READ MORE

3. Gap properties of helical edge states in two-dimensional topological insulators with time-dependent magnetic impurities
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics. A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect. READ MORE

4. Quantum teleportation of single-electron states
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : Quantum teleportation is a way to transfer a quantum state between two locations, by utilizing a shared entangled state, measurements and the ability to communicate measurement outcomes between the two locations. This thesis consists of a theoretical investigation of an experiment that would implement quantum teleportation using single-electron states in mesoscopic architectures. READ MORE

5. Wavefunction and spectral properties of single-particle emitters
University essay from Lunds universitet/Fysiska institutionenAbstract : The past six years have seen the development of fast and accurate single-particle sources, with possible applications in metrology, nanoelectronics, quantum information processing, and single-electron quantum optics. These mesoscopic devices also enable us to gain more insight into the quantum mechanics of interacting fermions. READ MORE
