The artifical gauge fields emerge from a closed, adiabatic curve in the parameter manifold of a waveguide system with degeneracies. An optimisation process allows to find ideal parameters of an experimental implementation. Additionally, two Lie-algebraic methods that solve the quantum master equation of an arbitrary, lossy waveguide system are developed, which allow to study non-Hermitian systems, e.g. parity-time-symmetry.<eng> vorgelegt von Lucas Teuber GutachterInnen: Stefan Scheel (Universität Rostock, Institut für Physik) ; Jan Wiersig (Universität Magdeburg, Institut für Physik) Dissertation Universität Rostock 2021 530 535.2 530 http://purl.uni-rostock.de/rosdok/id00003110 https://doi.org/10.18453/rosdok_id00003110 https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00003110-0 https://d-nb.info/1293534269/34 Non-Hermitian dynamics in lossy photonic waveguide systems--(DE-627)1767324537 urn:nbn:de:gbv:28-rosdok_id00003110-0 doi: 10.18453/rosdok_id00003110 oclc: 1263688697 ppn: (DE-627)1766558283
