摘要: Solid inflation can support a long period of anisotropic inflation. We calculate the statistical anisotropies in scalar and tensor power spectra their cross-correlation solid The tensor-scalar either be positive or negative, which impacts TT TB CMB map more significantly compared with self-correlation. spectrum contains potentially comparable contributions from quadrupole octopole angular patterns, is different scalar, bispectrum, where type anisotropy dominates over octopole.
