In a new FLEET theoretical study published recently in Physical Review Letters, the so called ‘smoking gun’ in the search for the topological magnetic monopole — also known as the Berry curvature — has been found.
The discovery is a breakthrough in the search for topological effects in non-equilibrium systems.
The group, led by UNSW physicist and Associate Professor, Dimi Culcer, identified an unconventional Hall effect, driven by an in-plane magnetic field in semiconductor hole systems that can be traced exclusively to the Berry curvature.
