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. 000150418 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000150418 590__ $$a1.5$$b2023 000150418 591__ $$aPHYSICS, MATHEMATICAL$$b27 / 60 = 0.45$$c2023$$dQ2$$eT2 000150418 591__ $$aPHYSICS, PARTICLES & FIELDS$$b19 / 31 = 0.613$$c2023$$dQ3$$eT2 000150418 591__ $$aPHYSICS, NUCLEAR$$b13 / 22 = 0.591$$c2023$$dQ3$$eT2 000150418 591__ $$aASTRONOMY & ASTROPHYSICS$$b54 / 84 = 0.643$$c2023$$dQ3$$eT2 000150418 592__ $$a0.404$$b2023 000150418 593__ $$aPhysics and Astronomy (miscellaneous)$$c2023$$dQ2 000150418 593__ $$aAstronomy and Astrophysics$$c2023$$dQ3 000150418 593__ $$aNuclear and High Energy Physics$$c2023$$dQ3 000150418 594__ $$a3.1$$b2023 000150418 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/submittedVersion 000150418 700__ $$0(orcid)0000-0002-2868-194X$$aLópez-Sarrión, Justo 000150418 700__ $$aMéndez, F. 000150418 700__ $$aTapia-Arellano, N. 000150418 773__ $$g38, 36n37 (2023), 7 pp.$$pMod.
