Why does the sign problem occur in evaluating the overlap of HFB wave functions?
Takahiro Mizusaki, Makito Oi, Noritaka Shimizu
For the overlap matrix element between Hartree-Fock-Bogoliubov states, there are two analytically different formulae: one with the square root of the determinant (the Onishi formul…
Toward extremes of angular momentum: Application of the Pfaffian algorithm in realistic calculations
Long-Jun Wang, Fang-Qi Chen, Takahiro Mizusaki +2
In a calculation of rotated matrix elements with angular momentum projection, the generalized Wick's theorem may encounter a practical problem of combinatorial complexity when the…
Grassmann integral and Balian-Brézin decomposition in Hartree-Fock-Bogoliubov matrix elements
Takahiro Mizusaki, Makito Oi, Fang-Qi Chen +1
We present a new formula to calculate matrix elements of a general unitary operator with respect to Hartree-Fock-Bogoliubov states allowing multiple quasi-particle excitations. The…
A new formulation to calculate general HFB matrix elements through Pfaffian
Takahiro Mizusaki, Makito Oi
A new formula is presented for the calculation of matrix elements between multi-quasiparticle Hartree-Fock-Bogoliubov (HFB) states. The formula is expressed in terms of the Pfaffia…
Norm-overlap formula of Hartree-Fock-Bogoliubov states with odd number parity
Makito Oi, Takahiro Mizusaki
A formula to calculate a norm overlap between Hartree-Fock-Bogoliubov (HFB) states with the odd number parity (one quasi-particle excited states) is derived with help of the Grassm…
Superdeformation in Asymmetric NZ Nucleus Ar
E. Ideguchi, S. Ota, T. Morikawa +15
A rotational band with five -ray transitions ranging from 2 to 12 states was identified in Ar. This band is linked through transitions from the excited 2$…
