Although the channel walls or secondary electron emission were not explicitly modeled, these simulations observed a strong electron drift instability in the azimuthal

Fortunately, the profile of the electric potential is far more sensitive to the presence of Berry curva- ture and one can therefore utilize it as an experimental tool to study
