In this work, we investigate a model of bounce inflation driven by the Higgs field. The Higgs field is non-minimally coupled with gravity through the Gauss-Bonnet term. We show that the Higgs field could drive a power-law contraction followed by a bounce and thereafter an inflationary phase with exit. The phases of contraction and inflation are obtained analytically. The smooth transition to the inflationary phase from contraction is obtained numerically. Further, the power-spectrum of the model is found to be consistent with the cosmological data.

Inflation with Gauss-Bonnet Correction and Higgs Potential
A quartic Higgs-like inflation model with a dilaton-like Gauss-Bonnet coupling reaches nS ≈ 0.973 and r ≈ 3.6×10⁻⁴ at 70 e-folds, within the ACT DR6 bounds, after a hand-tuned parameter scan.

Autonomous Dynamical System of Einstein-Gauss-Bonnet Cosmologies
A phase space analysis of Einstein-Gauss-Bonnet cosmology finds a stable equilibrium and a heteroclinic orbit, but the equilibrium requires the Gauss-Bonnet coupling to vanish and the orbit violates the Friedmann constraint.
