PrT sub(2)Al sub(20) (T=Ti, V) are ideal systems to study the quadrupole Kondo effect and quantum criticality arising from orbital degrees of freedom. The both systems have the nonmagnetic cubic Gamma sub(3) crystal electric field ground doublet with the well separated excited state. In particular,...
