Exploring three-dimensional quantum Griffiths singularity in bulk unconventional iron-based superconductors

Exploration of exotic quantum phase transitions has always been a focus in condensed matter physics. Critical phenomena in a phase transition are entirely determined by the universality class, which is controlled by the spatial and/or order-parameters and is independent of microscopic details.
