Description

<p>Understanding the quantum critical behavior in the vicinity of a quantum phase transition remains one of the major challenges of condensed matter physics. In particular, the unconventional criticality, which cannot be explained by the spin fluctuation theory, has attracted much attention in strongly correlated electron systems. In this article, we review our recent findings of a novel quantum phase transition and superconductivity associated with the valence or orbital instability in 4f-electron systems revealed by high pressure experiments.</p>
