A self-consistent calculation of nuclear matrix elements of the neutrinoless double-beta decays (0 nu beta beta) of Ge-76, Se-82, Zr-96, Mo-100, Cd-116, Te-128, Te-130, and Xe-136 is presented in the framework of the renormalized quasiparticle random phase approximation (RQRPA) and the standard QRPA. The pairing and residual interactions as well as the two-nucleon short-range correlations are for the first time derived from the same modern realistic nucleon-nucleon potentials, namely, from the charge-dependent Bonn potential (CD-Bonn) and the Argonne V18 potential. In a comparison with the traditional approach of using the Miller-Spencer Jastrow correlations, matrix elements for the 0 nu beta beta decay are obtained that are larger in magnitude. We analyze the differences among various two-nucleon correlations including those of the unitary correlation operator method (UCOM) and quantify the uncertainties in the calculated 0 nu beta beta-decay matrix elements.
