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.

Famous quotes containing the word modes:
“my brain
Worked with a dim and undetermined sense
Of unknown modes of being; o’er my thoughts
There hung a darkness, call it solitude
Or blank desertion.”
—William Wordsworth (1770–1850)
