Polarized backgrounds of relic gravitons
The polarizations of the tensor modes of the geometry evolving in cosmological backgrounds are treated as the components of a bispinor whose dynamics follows from an appropriate gauge-invariant action. This novel framework is closely analog to the (optical) Jones calculus and leads to a compact clas...

| description | The polarizations of the tensor modes of the geometry evolving in cosmological backgrounds are treated as the components of a bispinor whose dynamics follows from an appropriate gauge-invariant action. This novel framework is closely analog to the (optical) Jones calculus and leads to a compact classification of the various interactions able to polarize the relic gravitons. |
