Quantum simulations of warm dense matter dynamics using Bohm's trajectories

这些项目旨在探索利用玻姆对量子力学的解释来开发多电子系统动力学的数值方案的可能性。这样做的好处是，这些解决方案需要经典轨迹问题的解(分子动力学就是一个很好的例子)，但需要增加一个量子力来捕捉量子系统的非局域性质。可交付的项目是计算密集等离子体中的静态和动态结构因子。到目前为止，还没有人在等离子体代码中实现玻姆的量子方法。在凝聚态物质中已经尝试了这些方法，但完整的多体有限温度问题还没有完全解决。如果成功，这将是向前迈出的重要一步，该方法将与密度泛函理论竞争，但具有保持完整动力学行为的优势。该项目属于等离子体和激光领域。任何参与的公司或合作者-AWE公司。

The projects intends to explore the possibility of using Bohm's interpretation of quantum mechanics in order to develop a numerical scheme for the dynamics of many-electron systems. The advantage is that the solutions would requires the solution of a classical trajectory problem (for which molecular dynamics is a good example) but with the addition of a quantum force that capture the non-local properties of quantum systems.The projects deliverable is the calculation of static and dynamic structure factors in dense plasmas.So far no one has implemented Bohm's quantum approach in a plasma code. Approaches along these lines have been attempted in condensed matter, but the full many-body finite-temperature problem has not yet been fully tackled. If successful, this would represent a major step forward, with a method that is competitive against density functional theory but has the advantage of keeping the full dynamical behavior.This project falls within the Plasma and Lasers.Any companies or collaborators involved - AWE plc.
