| dc.description | We calculate the density of states $N$ and the the thermal conductivity $κ$ in layered superconductors for rotating in-plane magnetic field by using approximate analytical expressions for Abrikosov's vortex lattice state. For a gap with d$_{xy} $- orbital symmetry we find that the differences $ΔN$ and $Δκ$ between field directions parallel to the antinodes and parallel to the nodes of the gap are positive for lower fields and change sign for higher fields near $H_{c2} $. For increasing impurity scattering, $ΔN$ and $Δκ$ decrease due to a broadening of certain peaks in the angle-resolved density of states. The frequency dependencies of the amplitudes $ΔN$ and $Δκ$ exhibit similar crossover behavior at low frequencies which give rise to a sign change of $Δκ$ at low $T/T_c $. We conclude that variations of the specific heat and thermal conductivity can be observed only in the clean and low temperature limits. | |
