Classical and Stochastic Trans-Planckian Censorship
Omer Guleryuz
The trans-Planckian censorship conjecture (TCC) limits inflation to a deadline of e-folds. We formulate it in stochastic inflation as a bo…
Quantum Selection of Classical Histories
Omer Guleryuz
Can a finite quantum episode populate a classical future that the same prepared state never reaches deterministically? We show that it can, using inflation as a cosmological labora…
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…
Universal Nonminimal Coupling-to-Starobinsky Matching and a Single-Field Attractor
A. Savaş Arapoğlu, Sermet Çağan, 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…
Supersymmetric Horizons at the Edge of Effective Field Theory
Sermet Çağan, 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…
(Super)Universal Attractors and the de Sitter Vacua in String Landscape
Omer Guleryuz
In this work, we present an effective field theory for string inflation with spontaneously broken supersymmetry without generating any supersymmetric anti-de Sitter vacua. In that…
On the Trans-Planckian Censorship Conjecture and the Generalized Non-Minimal Coupling
Omer Guleryuz
We investigate the Trans-Planckian Censorship Conjecture (TCC) and the arising bounds on the inflationary cosmology caused by that conjecture. In that investigation, we analyze TCC…
A Solution to the de Sitter Swampland Conjecture versus Inflation Tension via Supergravity
Ugur Atli, Omer Guleryuz
The methods of supergravity allow us to derive a multi-field F-term potential. Using this, we denote a generic and non-positive single-field F-term potential. We insert our theory…
Off-Shell Linear Multiplets in Six Dimensions
Ugur Atli, Omer Guleryuz, Mehmet Ozkan
We provide a tensor calculus for -number of linear multiplets in six dimensions. The coupling of linear multiplets is encoded in a function ${\mathcal F}_{I…
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…
