Band mass anisotropy and the intrinsic metric of fractional quantum Hall systems
It was recently pointed out that topological liquid phases arising in the fractional quantum Hall effect (FQHE) are not required to be rotationally invariant, as most variational wave functions proposed to date have been. Instead, they possess a geometric degree of freedom corresponding to a shear deformation that acts like …
