罗洪刚

交叉学科研究中心主要研究方向： 1）强关联电子系统与高温超导 2）介观输运与动力学控制 3）密度矩阵重正化群算法与应用 4）量子信息与量子光学

罗洪刚中心开展的主要工作： 1）铜基高温超导体的微观模型研究（实验与理论的分析计算，很辛苦的工作且需要长期的积累）。 2）Kondo问题研究（自旋的屏蔽问题，曾或将在很多系统中观察到。实验现象丰富，但真正的理论进展并不容易）。 3）量子化学密度矩阵重正化群算法研究和应用（一项从2004年就开始的工作，...)。 4）量子退相干和纠缠动力学（量子信息，量子计算实现之前必须解决的问题 ... )。 5）非自治（或时间相关）量子系统的动力学控制（好像跟现代技术的发展与认识自然和改造自然的理念有关）。
