QLS applied to single- and multi-reference linearized coupled cluster shows polylog κ and sublinear sparsity on model systems, supporting prospects of exponential advantage over conjugate gradient.
We find that for the specific matrices that we 11 are interested in the context of LCC (SR as well as icMR), dmax dmin is one such quantity, as shown in Figs
