It is proved that many-particle Bohm trajectories can be computed from single-particle time-dependent Schrödinger equations. From this result, a practical algorithm for the computation of transport properties of many-electron systems with exchange and Coulomb correlations is derived. As a test, two-particle Bohm trajectories in a tunneling scenario are compared to exact results with an excellent agreement. The algorithm opens the path for implementing a many-particle quantum transport (Monte Carlo) simulator, beyond the Fermi liquid paradigm.
事实证明，多粒子玻姆轨迹可以从单粒子含时薛定谔方程计算得出。基于这一结果，推导出了一种用于计算具有交换和库仑关联的多电子系统输运性质的实用算法。作为测试，将隧穿场景下的双粒子玻姆轨迹与精确结果进行了比较，二者吻合度极高。该算法为超越费米液体范式实现多粒子量子输运（蒙特卡罗）模拟器开辟了道路。
