## Appendix A: Convergence in the RVM basis 

In this section, we analyze in detail the convergence properties of the RVM diagonalization for the yrast state of N = 5 bosons with L = 8 (a case associated with a Moore-Read function) that was discussed in Sec. III D. 

In Table VI, we display the coupling matrix elements for the contact interaction between the RVM basis func- tions given in Eq. (51). The convergence properties in the RVM basis cannot be immediately seen from an in- spection of these coupling matrix elements; while most of the off-diagonal elements in TABLE VI are smaller than the differences between the associated diagonal elements, a couple of them are indeed larger.

The fast-convergence properties of the RVM basis can be seen through a tabulation of the intermediate RVM- diagonalization total energies as the size of the RVM basis increases in successive steps. In TABLE VII, in addition to these intermediate RVM energies, we also display the corresponding relative error (relative to the EXD result) and the corresponding overlap with the EXD wave func- tion for the yrast state (denoted by the index [1] in Sec. III D). 

We stress that convergence (as a function of the num- ber of the RVM basis functions used in the calculation) is seen from TABLE VII to be achieved rapidly (i.e., al- ready with the use of only two basis functions one obtains a relative error of 1.6% for the energy eigenvalue, and a 99% overlap with the exact eigenfunction). In particular, we note that at the second step the RVM wavefunction is already more accurate compared to the Moore-Read function which exhibits a relative error of 6.5% for the energy and an overlap of 91.3% [see TABLE VII]. 

In this section, we analyze in detail the convergence properties of the RVM diagonalization for the yrast state of N = 4 electrons with L = 18 (a case associated with a Jastrow-Laughlin function) that was discussed in Sec. III C.
