Quantum Fluctuations and Transport Phenomena in Fermionic Systems with Charge Frustration

我们研究了表示导电电子的各种模型和几何挫折晶格上的变化顺序。我们研究了挫折和自由度变化、输运现象以及电子结构之间的相互作用。结果发现，在量子临界点或BKT跃迁后，会形成异常电荷有序态和部分无序态。我们澄清了这些新状态只有通过受挫电荷自由度才能稳定。

We studied various models representing conduction electrons and chage orderings on geometrically frustrated lattices. We investigated interplay between frustrations and chage degrees of freedom, transport phenomena as well as electronic structures. As a result, we found that anomalous charge-ordered states as well as partially disordered states are formed after quantum critical points or BKT transitions. We clarified that these novel states are stabilized only through frustrated charge degrees of freedom.
