Nonequilibrium dynamics of the $σ$-model modes on the de Sitter space
The two-dimensional $σ$-model with the de Sitter target space has a local canonical description in the north pole diamond of the Penrose diagram in the cosmological gauge. The left and right moving modes on the embedded base space with the topology of a cylinder are entangled among themselves and in...
