First, single-cycle excitation clarifies the insulator-to-metal transition mechanism in M1-VO₂ by separating electronic and structural dynamics and revealing the anharmonic V–V bond oscillation central to the phase change. Second, it details the development of a solid-state high harmonic spectroscopy apparatus that enables precise study of the transition from perturbative to nonperturbative or extreme nonlinear optics in bulk crystals for the first time.<eng> Open Access Urheberrechtsschutz 1.0 vorgelegt von Santanu Mandal GutachterInnen: Eleftherios Goulielmakis (Institut für Physik, Universität Rostock) ; Thomas Brabec (Department of Physics, University of Ottawa) Dissertation Universität Rostock 2025 530 https://purl.uni-rostock.de/rosdok/id00005659 Single-cycle probing of the dynamics of the insulator-to-metal phase transition in VO₂--(DE-627)197601753X urn:nbn:de:gbv:28-rosdok_id00005659-0 doi: 10.18453/rosdok_id00005659 oclc: 1602639160 ppn: (DE-627)1976016207
