Outline of Final Research Achievements |
It is shown to be understood theoretically in the natural and unified way from the viewpoint of the quantum critical phenomena of Yb-valence fluctuations that the mechanism of emergence of zero-tuning unconventional quantum criticality as well as its robustness under pressure in the heavy-electron quasicrystal Yb15Al34Au51 and the origin of emergence of the T/B scaling over four decades observed in the magnetization data in beta-YbAlB4.
