Development in calculations for electronic states near the quantum critical point in strongly correlated f-electron systems

点击翻译按钮获取中文摘要

Novel physical properties in many strongly correlated electronsystems are realized when a several ground states are competingin a certain parameter. A large Coulomb interaction plays a important role even in lower symmetry system. A computer code for performing calculations of such the electronic states, have been developed, considering the real symmetry. The electronic statesof UCoAl, which shows quantum critical phenomena under pressure, and other systems have been studied.
