@Book{1976016207, author="Mandal, Santanu", title="Single-cycle probing of the dynamics of the insulator-to-metal phase transition in VO$_2$", year="2025", address="Germany; Rostock", abstract="This thesis uses single-cycle and few-cycle femtosecond pulses to explore two major frontiers in condensed-matter and strong-field physics. First, single-cycle excitation clarifies the insulator-to-metal transition mechanism in M1-VO$_2$ 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.", school="Universit{\"a}t Rostock", note="vorgelegt von Santanu Mandal", note="GutachterInnen: Eleftherios Goulielmakis (Institut f{\"u}r Physik, Universit{\"a}t Rostock) ; Thomas Brabec (Department of Physics, University of Ottawa)", note="Dissertation Universit{\"a}t Rostock 2025", doi="10.18453/rosdok_id00005659", url="https://purl.uni-rostock.de/rosdok/id00005659", url="https://doi.org/10.18453/rosdok_id00005659", language="English" }
