- Description
- Quantum-mechanical systems that break a symmetry of its classical action are called quantum anomalous. Such systems challenge our understanding of fundamental physics and enable exotic and potentially useful response properties. While first predicted in the elementary-particle quantum field theory for hypothetical massless fermions, quantum anomalies have been already realized in condensed matter, where the massless fermions arise as topologically protected quasiparticles. In this talk I will present some of our recently predicted anomaly-related phenomena in nanostructures of anomaly-hosting materials. In particular, I will discuss two different nanostructure setups, one showing characteristic quantum-oscillation signatures that you would not expect, and, another setup, showing a characteristic absence of quantum oscillations likewise unexpected. .
