Title: Collective Mode in a Superconductor with Mixed-Symmetry Order Parameter Components

Abstract

We consider a superconducting state with mixed-symmetry order parameter components, e.g., d+is or d+id{sup '} with d{sup '}=d{sub xy} . We argue for the existence of a new orbital magnetization mode which corresponds to oscillations of relative phase {phi} between two components around an equilibrium value of {phi}=({pi}/2) . It is similar to the ''clapping'' mode in superfluid {sup 3}He- A . We estimate the frequency of this mode {omega}{sub 0}(B, T) depending on the field and temperature for the specific case of magnetic field induced d{sup '}=d{sub xy} state. This mode is tunable with a magnetic field with {omega}{sub 0}(B, T)(propor to)B{delta}{sub 0} , where {delta}{sub 0} is the magnitude of the d -wave order parameter. We also estimate the velocity s(B, T) of this mode. (c) 2000 The American Physical Society.
