Microscopic calculation of symmetry projected nuclear level densities

Abstract
We present a quantum Monte Carlo method with exact projection on parity and angular momentum that is free of a sign problem for seniority-conserving nuclear interactions. This technique allows the microscopic calculation of angular momentum and parity-projected nuclear level densities. We present results for the $^{55}\mathrm{Fe}$, $^{56}\mathrm{Fe}$, and $^{57}\mathrm{Fe}$ isotopes. Signatures of the pairing phase transition are observed in the angular momentum distribution of the nuclear level density.
