    "abstract": "We perform Shell Model Monte Carlo calculations of selected N=Z pf-shell\nnuclei with a schematic hamiltonian containing isovector pairing and\nquadrupole-quadrupole interactions. Compared to realistic interactions, this\nhamiltonian does not give rise to the SMMC ``sign problem\u0027\u0027, while at the same\ntime resembles essential features of the realistic interactions. We study\npairing correlations in the ground states of N=Z nuclei and investigate the\nthermal dependence of selected observables for the odd-odd nucleus Co54 and the\neven-even nuclei Zn60 and Ni60. Comparison of the present results to those with\nthe realistic KB3 interaction indicates a transition with increasing\ntemperature from a phase of isovector pairing dominance to one where isoscalar\npairing correlations dominate. In addition, our results confirm the qualitative\nreliability of the procedure used to cure the sign problem in the SMMC\ncalculations with realistic forces.",
