标题： Time-dependent covariant density functional theory in 3D lattice space: benchmark calculation for 16O + 16O reaction

摘要： 在三维坐标空间中，在没有任何对称性限制的情况下，基于成功的密度泛函PCPK1，发展了时变协变密度泛函理论，并系统地进行了16O+16O反应的基准计算。 相对论动力学、动量守恒定律、总能量守恒定律和粒子数守恒定律以及时间反演不变性被检验并确认在数值上得到满足。 包括耗散动力学和垒上融合截面在内的两个主要应用被展示。 所得结果与非相对论时变密度泛函理论的结果以及现有数据有很好的一致性。 这表明新发展的时变协变密度泛函理论可以作为未来核动力学过程研究的有效方法。 显示英文摘要

摘要： 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.
