在含时正则基中，对势为对角势的近似下，得到了含时Hartree-Fock-Bogoliubov（TDHFB）理论的正则基形式.正则基公式显著降低了计算成本。我们应用该方法的偶-偶核的线性响应计算。系统地计算了富质子Mg同位素的E1强度分布。计算结果表明滴线核巨偶极共振存在强的朗道阻尼。
A canonical-basis formulation of the time-dependent Hartree-Fock-Bogoliubov (TDHFB) theory is obtained with an approximation that the pair potential is assumed to be diagonal in the time-dependent canonical basis. The canonical-basis formulation significantly reduces the computational cost. We apply the method to linear-response calculations for even-even nuclei. E1 strength distributions for proton-rich Mg isotopes are systematically calculated. The calculation suggests strong Landau damping of giant dipole resonance for drip-line nuclei.
