Over the past two years, we comprehensively characterized the field-induced quantum criticality of the multipolar Kondo system PrV2Al20 using electrical transport and thermodynamic probes. We succeeded in detecting universal scaling in magnetoresistance, Shubnikov-de Haas oscillations, and a drastic rise in the Hall coefficient on approaching the quantum critical regime. We further performed low-temperature and high-field specific heat and magnetization measurements, which yielded high-precision thermodynamic information on the non-Fermi liquid phase intrinsic to the multipolar Kondo effect. This study leads to profound insights into the non-Fermi-liquid behavior generated by the multipolar Kondo effect and the changes in Fermi surface properties near the multipolar quantum critical point.
