On the analogue of Einstein-Gauss-Bonnet theory in 3+1 dimensions
Giorgi Tukhashvili
Higher curvature corrections to the Einstein-Hilbert term may play an important role in probing the strong-field regime of gravity. In this letter, we demonstrate that the local ef…

Weakly-Coupled Trace Anomaly Action for Gravity
Gregory Gabadadze, Giorgi Tukhashvili
We discuss a local, diff-invariant quantum effective action for gravity that captures the trace anomaly via a counter-term. We discuss why this counter-term is the most significant…

Cosmological Bounces Induced by a Fermion Condensate
Giorgi Tukhashvili, Paul J. Steinhardt
We show that it is possible for fermion condensation of the Nambu-Jona-Lasinio type to induce a non-singular bounce that smoothly connects a phase of slow contraction to a phase of…
