论文摘要
具有成功密度功能PCPK1的时间依赖性协变量功能理论是在三维坐标空间中开发的，而无需任何对称限制，并且系统地进行了16o + 16o反应的基准计算。检查并确认相对论的运动学，动量，总能量和粒子数的保护定律以及时间转换不变性并确认为数值满足。说明了两个主要的应用，包括耗散动力学和上面的熔点融合横截面。获得的结果与非依赖时间依赖性密度功能理论和可用数据给出的结果非常吻合。这表明，新开发的时间依赖性的协变量密度功能理论可以作为对核动力学过程未来研究的有效方法。
Time-dependent covariant density functional theory with the successful density functional PCPK1 is developed in a three-dimensional coordinate space without any symmetry restrictions, and benchmark calculations for the 16O + 16O reaction are performed systematically. The relativistic kinematics, the conservation laws of the momentum, total energy, and particle number, as well as the time-reversal invariance are examined and confirmed to be satisfied numerically. Two primary applications including the dissipation dynamics and above-barrier fusion cross sections are illustrated. The obtained results are in good agreement with the ones given by the nonrelativistic time-dependent density functional theory and the data available. This demonstrates that the newly developed time-dependent covariant density functional theory could serve as an effective approach for the future studies of nuclear dynamical processes.
