中文摘要：

强关联体系有着非常丰富的物理现象和复杂的相图，而量子相变往往进一步放大了强关联体系中巨大的量子效应，引起更加丰富和非常规的物性。我们建议开展强关联电子体系的量子相变及反常物性的研究。通过研究与莫特(Mott)物理相关的相变现象、不同自旋态间的量子相变、以及由几何结构引起的强量子涨落体系中的量子相变或临界行为，总结在强关联电子体系中，量子相变和金属－绝缘体转变的调控参数是如何影响其电子结构、输运性质的，理解这些体系中巨大的量子效应的机理。通过调控成分、温度、磁场、电场、光场、压力和同位素的置换等参数来控制量子相变和金属－绝缘体转变，从而研究其电子结构和输运性质等物理行为。揭示强关联体系中量子相变的普遍物理规律，指导未来相关宏观量子效应的应用。
