摘要：

We have calculated all order-parameter collective modes and their contributions to the spin and charge susceptibilities for possible p-wave pairing states in Sr2RuO4. The susceptibilities are calculated for pairing states having gaps without and with nodes, and for wave vectors q=0 and nesting vector q=Q associated with the alpha and beta bands of Sr2RuO4. Important for the observability of the spin-fluctuation modes, for example, by spin resonance or neutron scattering, and of the charge-fluctuation modes by ultrasound, is the effect of quasiparticle damping. This effect is taken into account and discussed in connection with recent neutron-scattering data on Sr2RuO4.
