Microscopic Mechanism and Pairing Symmetry of Superconductivity in the Noncentrosymmetric Heavy Fermion Systems CeRhSI3 and CeIrSi3

We study the pairing symmetry of the noncentrosymmetric heavy fermion superconductors CeRhSi 3 and CeIrSi 3 under pressures, which are both antiferromagnets at ambient pressure. We solve the Eliashberg equation by means of the random phase approximation and find that the mixed state of extended s - and p -wave rather than the d + f wave state could be realized by enhanced antiferromagnetic spin fluctuations. It is elucidated that the gap function has line nodes on the Fermi surface and the resulting density of state in the superconducting state shows a similar character to that of usual d -wave superconductors, resulting in the NMR relaxation rate 1/( T 1 T ) that exhibits no coherence peak and behaves like 1/( T 1 T )∝ T 2 at low temperatures.We study the pairing symmetry of the noncentrosymmetric heavy fermion superconductors CeRhSi
