Abstract
We show that an induced -wave harmonic in the superconducting gap of an orthorhombic superconductor strongly affects the excitation spectrum near a twinning plane. In particular, it yields bound states of zero energy with areal density proportional to the relative weight of the -wave component. An unusual scattering process responsible for the thermal conductivity across the twin boundary at low temperatures is also identified.
