    "abstract": "Applying the thermo field dynamics, we reformulate exact quantum number\nprojection in the finite-temperature Hartree-Fock-Bogoliubov theory. Explicit\nformulae are derived for the simultaneous projection of particle number and\nangular momentum, in parallel to the zero-temperature case. We also propose a\npractical method for the variation-after-projection calculation, by\napproximating entropy without conflict with the Peierls inequality. The quantum\nnumber projection in the finite-temperature mean-field theory will be useful to\nstudy effects of quantum fluctuations associated with the conservation laws on\nthermal properties of nuclei.",
