Skyrmions in Quantum Hall Ferromagnets

Post date: December 28, 2020

Rotating microtraps provide a promising setting for realizing quantum Hall physics with contact interactions using ultracold atoms. While bosonic systems with contact interactions have been studied intensively, the fermionic case remained widely unexplored in this context.

In a collaboration with the University of Heidelberg, we show that quantum Hall ferromagnetism can be explored in rotating microtraps. Specifically we propose an adiabatic preparation scheme for skyrmions - topological magnetic textures - in these systems.
