Complex Behaviour in Classical and Quantum Chaos I shall first explain how chaotic behaviour can emerge in deterministic systems of classical dynamics. It is due to a sensitive dependence on initial conditions, meaning that two nearby initial states of a system develop in time such that their positions (states) separate very fa ... more |

Polyhydrides with mysterious structures and detection of their superconductivity by radio-frequency methods Pressure-stabilized hydrides are a new rapidly growing class of high-temperature superconductors. The remarkable properties of H$_3$S (T$_c$ = 200 K), YH$_6$ (T$_c$ = 224 K) and LaH$_{10}$ (T$_c$ = 250 K) at 130-200 GPa catalyzed the search for superconductivity in compressed ter ... more |

Light Scattering in Nanophotonic Systems Gustav Mie outlined more than 100 years ago a quasi-analytical solution for light scattering at a sphere. It constitutes a algebraic solution to Maxwell’s equations, where the incident and scattered fields are expanded into a suitable basis set. A matrix then expresses the rela ... more |

Atomic and Molecular Physics of Astronomical Spectra The desire to characterize and model the atmospheres of the many extrasolar planets that have been discovered over the last three decades is a major driver of current astronomy. This goal is impacted by the lack of spectroscopic data for the molecules (and to a lesser extent atom ... more |

Quantum state control of a ground state H$_2$ molecule. Measurements of quantum-state-controlled collisions between gas phase molecules, and between molecules and surfaces, provide the ultimate test for theoretical modelling. Over the years many techniques have been developed to control the quantum states of the impinging molecules, w ... more |

Following complex spin structures in time and space Controlling ultrafast spin dynamics directly on the quantum level by femtosecond light pulses promises a dramatic increase in speed, energy efficiency, and density of how we transport, process, and store information. Recent advances in the field have enabled an understanding of l ... more |

The Helmholtz Zentrum Dresden Rossendorf – research for next generations The Helmholtz-Zentrum Dresden - Rossendorf e.V. (HZDR) as a multiprogrammatic, interdisciplinary, and internationally active national laboratory and member of the Helmholtz Association will be presented in this lecture. With about 1,500 employees and an annual budget of around ₠... more |

Intertwined relaxation processes & athermal electron distributions in laser-excited solids Femtosecond laser pulses irradiating a solid material induce a cascade of processes starting with the excitation of so-called hot electrons and passing through various relaxation processes. Several scattering mechanisms act on different timescales. At sufficiently high energy den ... more |

The complex dynamics of Fermi Pasta Ulam Tsingou process revealed in optical fiber systems The Fermi–Pasta–Ulam–Tsingou (FPUT) recurrence process is a universal phenomenon that describes the natural cycle through which a nonlinear system returns to its initial state after undergoing complex coupling dynamics. This phenomenon can be observed in optical fibers by l ... more |

Electron dynamics and correlation in novel quantum materials The collective behaviour of electrons in strongly correlated materials gives rise to fascinating
quantum phases, including correlated insulators, charge-density waves, superconductors, and spin
liquids. These phases are highly sensitive to external control parameters such as pr ... more |
