Determining gap nodal structures in Fe-based superconductors: Theory of the angle dependence of the low-temperature specific heat in an applied magnetic field
Since the discovery of high-${T}_{c}$ ${\mathrm{LaO}}_{1\ensuremath{-}x}{\mathrm{F}}_{x}\mathrm{FeAs}$ and other such systems based on $\mathrm{FeAs}$ layers, several proposals have been made for the superconducting order parameter ${\ensuremath{\Delta}}_{\mathbf{k}}$, on both phenomenological and microscopic grounds. Here we discuss how the symmetry of ${\ensuremath{\Delta}}_{\mathbf{k}}$ in the bulk can be determined, assuming that single crystals will …
