Universal Nonminimal Coupling-to-Starobinsky Matching and a Single-Field Attractor
A. SavaÅ ArapoÄlu, Sermet ÃaÄan, Omer Guleryuz +1
We establish an off-shell commutativity theorem in 4D parity-even quadratic gravity that the Hubbard-Stratonovich/Legendre lifts, algebraic elimination of auxiliaries, including th…
Stochastic Survival near Swampland Boundaries
Omer Guleryuz
Swampland and compactification data tell us where a chosen EFT description can lose parametric control; stochastic cosmology asks which histories survive near that edge. We turn th…
String Thresholds, Dynamical Gauss--Bonnet Couplings, and Starobinsky Attractors
Omer Guleryuz
We develop a string-motivated dynamical Gauss--Bonnet completion of Starobinsky inflation. Since a constant Gauss--Bonnet term is topological in four dimensions, observable effects…
Supersymmetric Horizons at the Edge of Effective Field Theory
Sermet ÃaÄan, Omer Guleryuz, Cemal Berfu Senisik
What if supersymmetry is not something to be hidden, but something to be reached? We introduce the Supersymmetric Horizon Stabilization (SHS): a conceptually unified and analytical…
