abstract

Motivated by the coincidence of scrambling time in de Sitter and maximum lifetime given by the $\textit{Trans-Planckian Censorship Conjecture}$ (TCC), we study the relation between the de Sitter complementarity and the Swampland conditions. We study thermalization in de Sitter space from different perspectives and show that TCC implies de Sitter space cannot live long enough to be considered a thermal background. We also revisit $\alpha$-vacua in light of this work and show that TCC imposes multiple initial condition/fine-tuning problems on any conventional inflationary scenario.

  1. Alice in Warpland: KK modes, Warped Compactifications and the Swampland

    hep-th 2026-03 unverdicted novelty 7.0 of 10

    In codimension-one warped compactifications with exponential potentials, the KK mass decay rate λ_KK is reduced by warping but still satisfies the Sharpened Distance Conjecture precisely when the higher-dimensional po...

  2. Stochastic Survival near Swampland Boundaries

    hep-th 2026-06 unverdicted novelty 6.0 of 10

    A stochastic survival framework maps swampland control data to conditioned drifts for moduli histories near boundaries via the Doob transform, yielding a universal inward wall response near regular hard boundaries.

  3. Stochastic Survival near Swampland Boundaries

    hep-th 2026-06 conditional novelty 4.0 of 10

    Surviving inflationary histories develop a universal inward drift near any hard swampland boundary — two times the diffusion over the distance to the edge — regardless of the cutoff's microscopic origin.
