| Research Abstract |
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.
