Cavity-mediated attractive interactions enhance the fractional quantum Hall transport gap with a quadratic electron-number scaling and a fourth-power dependence on the vacuum-field gradient, as shown by composite-fermion calculations.
It is particularly convenient as at the appropriate magnetic flux, the fractional quantum Hall ground state is nondegenerate
