Abstract
We study two distinct systems along a similar theme. In one, we present new theoretical studies of the optical properties of the $J_2$-$\lambda$ model for the materieal FeSc$_2$S$_4$, which places it close to a quantum critical point on the disordered side of a quantum phase transition between a N
