New Bardeen-Cooper-Schrieffer-type theory at finite temperature with particle-number conservation
H. Nakada, K. Tanabe
We formulate a new Bardeen-Cooper-Schrieffer (BCS)-type theory at finite temperature, by deriving a set of variational equations of the free energy after the particle-number projec…

Effects of particle-number conservation on heat capacity of nuclei
K. Esashika, H. Nakada, K. Tanabe
By applying the particle-number projection to the finite-temperature BCS theory, the -shaped heat capacity, which has recently been claimed to be a fingerprint of the superfluid…

Quantum number projection at finite temperature via thermofield dynamics
K. Tanabe, H. Nakada
Applying the thermo field dynamics, we reformulate exact quantum number projection in the finite-temperature Hartree-Fock-Bogoliubov theory. Explicit formulae are derived for the s…
