报告1地点:理学楼103

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


报告人简介:

Uli Zeitler (1964, Schaffhausen, Switzerland) is a full professor (Hoogleraar) at the High Field Magnet Laboratory (HFML-EMFL) of Radboud University in Nijmegen, the Netherlands. He joined High Field Magnet Laboratory as an Associate Professor in 2002 and was actively involved in transforming it from a national research laboratory into a world-leading internationally recognized facility. He has published more than 170 papers in the fields of semiconductors, nanostructures, magnetism and superconductivity, with citations more than 12,000 according to Google Scholar.
