Exploring unconventional superconductivity in the topological 3D Dirac Semimetal PdTe
Abstract: PdTe is a 3D Dirac semimetal, exhibiting type- II superconducting behavior with a transition temperature (Tc) ? 4.5 K. Recent angle-resolved photo-emission spectroscopy (ARPES) experiments have revealed the coexistence of bulk-nodal and surface-nodeless cooper pairings in PdTe. Our field-dependent specific heat data down to temperatures around ? 58 mK shows a power-law field dependence, which differs from the usual linear behavior expected for an isotropic fully gapped s-wave superconductor. Additionally, our zero-field specific heat data reveals a clear ? T^3 temperature dependence at low temperatures (T < Tc/3), suggesting the presence of bulk point nodes in the superconducting order parameter of PdTe. We propose a muon-spin rotation (?SR) study to probe time reversal symmetry breaking and the superconducting energy gap symmetry in single crystal PdTe.
