Query: Evidence of Nodal Line in the Superconducting Gap Symmetry of
  Noncentrosymmetric ThCoC$_{2}$   The newly discovered noncentrosymmetric superconductor ThCoC$_{2}$ exhibits
numerous unconventional behavior in the field dependent heat capacity data.
Here we present the first measurement of the gap symmetry of ThCoC$_{2}$ by
muon spin rotation/relaxation $(\mu$SR) measurements. Temperature dependence of
the magnetic penetration depth measured using the transverse field $\mu$SR
measurement reveal the evidence of nodal pairing symmetry. To understand these
findings, we carry out the calculations of superconducting pairing eigenvalue
and eigenfunction symmetry due to the spin-fluctuation mechanism, by directly
implemented the {\it ab-initio} band structures. We find that the system
possesses a single Fermi surface with considerable three-dimensionality, and
hence a strong nesting along the $k_z$-direction. Such a nesting promotes a
superconducting pairing with a $\cos{k_z}$-like symmetry with a prominent nodal
line on the $k_z=\pm\pi/2$ plane. The result agrees well with the experimental
data.
