报告1摘要：In the first lecture I will introduce into the fundamental effects of high magnetic fields on matter and exemplify them with some specific examples. Specifically, I will cover:
- Generation of high magnetic fields
- Forces and torque on magnetic moments: Magnetic levitation and orientation:
- Form conventional to molecular magnets
- Lorentz force: Classical Hall effect in single-band and multi-band systems
- Magnetic fields & quantum mechanics: canonical momentum & Landau quantisation
- Quantum Hall effects in two-dimensional electron systems

报告2摘要：The second lecture is then devoted to deepen the fundamental knowledge gained in the first lecture and give a short idea on some contemporary high-field experiments in new material systems. I will start with discussing rather generally the (non-conventional) bandstructure in materials and elucidate how this can lead to spectacularly new physics. Subsequently I will discuss this physics in some specific material systems in some more detail.
- Magneto-quantum oscillations: Shubnikov-de-Haas and de-Haas-van Alphen effects used to uncover the band-structure of materials (Fermiology)
- Graphene – a zero-gap semiconductor with chiral linearly dispersing quasi-particles
- Dirac systems in the bulk: From finite-gap to zero-gap semiconductors
- Weyl fermions in semimetals: Addressing the bandstructure using high fields
- Fermiology beyond quantum oscillation
