We study the general properties of attractors in a cosmological model with tachyonic potential and a scalar field non-minimally coupled to matter. A general analytic formulation is given to derive fixed points with a discussion on their stability. We also check the consistency of the model by fitting it to the supernovae type Ia data.

  1. Kinetic coupled tachyon: A dynamical system analysis

    gr-qc 2024-12 conditional novelty 6.0 of 10

    A kinetically coupled tachyon dark energy model admits a new stable scaling attractor for a range of coupling and potential parameters, providing a mechanism to keep dark energy and dark matter densities comparable.

  2. Accelerating scaling solutions from dark matter particle creation

    gr-qc 2026-04 unverdicted novelty 5.0 of 10

    Accelerating scaling attractors without dark energy appear only when the interaction is controlled by DM density and energy flows from DM to a barotropic fluid.
