By means of high-pressure resistivity measurements on single crystals, we investigate the charge transport properties ${\mathrm{Cu}}_{x}{\mathrm{PdTe}}_{2}$, notable for combination topological type-II Dirac semimetallic with superconductivity up to ${T}_{c}=2.5\phantom{\rule{0.16em}{0ex}}\mathrm{K}$. In both pristine $(x=0)$ and intercalated $(x=0.05)$ samples, find an unconventional ${T}^{4}$...
