We study runaway, kination-dominated epochs in string cosmology. We show how the apparent classical decompactification runaway of the volume modulus, described by a kination epoch in the 4-dimensional EFT, can be uplifted to a classical Kasner solution in 10d in which the non-compact dimensions collapse towards a Big Crunch. This can also be generalised for arbitrary spacetime and compactification dimensions. We conclude with some comments on how this picture is modified by quantum effects, and the need for both dynamical and kinematical Swampland constraints.

  1. Self-Tracking Solutions for Asymptotic Scalar Fields

    hep-th 2025-07 conditional novelty 7.0 of 10

    The self-perturbations of a scalar field on an exponential potential can act as an effective radiation background, producing a self-tracking solution with the familiar radiation tracker fixed point.

  2. Background instability of quintessence model in light of entropy and distance conjecture

    hep-th 2026-01 conditional novelty 6.0 of 10

    An entropy comparison shows quintessence backgrounds with a finite event horizon are unstable, equating the trans-Planckian censorship bound with a species-entropy growth condition.

  3. Coexisting Flux String Vacua from Numerical K\"ahler Moduli Stabilisation

    hep-th 2025-07 conditional novelty 5.0 of 10

    Numerical scans of Type IIB compactifications find single scalar potentials containing coexisting KKLT/LVS and Kahler-uplifted/LVS minima, including AdS, Minkowski, and dS pairs.
