Spontaneous symmetry breaking and the cosmological constant

Gamboa, J. ; López-Sarrión, Justo ; Méndez, F. ; Tapia-Arellano, N.

Resumen: An approach that allows studying the relationship between the neutralization of the cosmological constant and instantons for cosmology coupled to antisymmetric fields is proposed. Using suitable variables, the Lagrangian leading to the FRW equations can be written analogously to a Ginzburg–Landau theory, and we show how spontaneous symmetry breaking appears.
