RT Journal Article T1 Towards geometric inflation: The cubic case A1 Arciniega, Gustavo A1 Edelstein Glaubach, José Daniel A1 Jaime, Luisa G. K1 Higher-curvature gravity K1 Einsteinian Cubic Gravity AB We present an up to cubic curvature correction to General Relativity with the following features: (i) its vacuum spectrum solely consists of a graviton, (ii) it possesses well-behaved black hole solutions which coincide with those of Einsteinian cubic gravity, (iii) its cosmology is well-posed as an initial value problem and, most importantly, (iv) it entails a geometric mechanism triggering an inflationary period in the early universe (driven by radiation) with a graceful exit to a late-time cosmology arbitrarily close to ΛCDM.
