Cubic CeZn shows a structural phase transition under pressure and it modifies the ground state from an antiferromagnetic (AFM) to ferromagnetic (FM) state. To investigate how FM terminates at quantum transition, we measured electrical resistivity for single-crystal CeZn. The temperature into decreases monotonously with increasing pressure, accompanied by pronounced Kondo effect, but drastic cha...

Quantum phase transitions are highly relevant to current research efforts in both superconductivity and quantum information. Numerical renormalization group (NRG) studies of quantum impurity models near a quantum critical point have given us a theoretical understanding of many low-temperature systems, successfully explaining the experimental properties of certain superconducting materials and q...
