Topology in the Quantum Limit
ORAL
Abstract
Extreme magnetic fields play a fundamental role in both identifying and inducing novel states of matter. I will discuss the experimental challenges and rewards of subjecting low carrier density metals to high fields.
Beyond Landau level spectroscopy of the Fermi surface morphology and topology, I will discuss recent examples of novel physics in the quantum limit – where the cyclotron energy not only approaches, but exceeds the Fermi energy – from Hall quantization in three-dimensional Dirac systems, to the realization of the chiral anomaly in Weyl semimetals and the distinct possibility of inducing new correlated states of matter in topologically non-trivial metals.
