In an arXiv preprint, José I. Latorre and Germán Sierra made the following conjecture about the upper bound of the central charge for quantum critical lattice Hamiltonians with nearest-neighbor interractions in one dimension:


 * If the local Hilbert space dimension of the lattice model is $$d$$, the maximal central charge that the model can reach is $$c_{\mathrm{max}} = d-1$$.
