This project deals with the development and applications of semiclassical methods in physical systems with higher symmetries. Semiclassical methods provide an efficient way of understanding multi-particle systems in limits where the computational cost of exact calculations would be prohibitive.******The end goals of the project are applications to SU(3) and SU(4) systems, but a number of tools must be developed before the application stage can be reached. Examples of systems with SU(3) or SU(4) symmetries include 3-well Bose-Einstein condensates and some superconductors.

本计画探讨半经典方法在具有较高对称性的物理系统中的发展与应用。 半经典方法提供了一种有效的方法来理解多粒子系统的限制，其中精确计算的计算成本将是禁止的。该项目的最终目标是应用于SU（3）和SU（4）系统，但在应用阶段之前必须开发一些工具。 具有SU（3）或SU（4）对称性的系统的例子包括3阱玻色-爱因斯坦凝聚和一些超导体。
