Tensor Modes
The presence of primordial tensor fluctuations (manifested as gravitational waves) is predicted by many inflationary models. As with scalar fluctuations, tensor fluctuations are expected to follow a power law and are parameterized by the tensor index (the tensor version of the scalar index), and the ratio of the tensor to scalar power.
