| Research Abstract |
With comprehensive use of several techniques of quantum beam spectroscopy we systematically studied charge and spin excitations or correlations which strongly couple each other in strongly correlated electron systems. These studies revealed dual nature or hierarchy in charge excitations which will provide an important clue to understand the origin of diverse properties in this systems.
