We construct the world-volume action for non-BPS D-branes in type II string theories. This action is invariant under all the unbroken supersymmetries in the bulk, but these symmetries are realised as spontaneously broken symmetries in the world-volume theory. Coupling of this action to background supergravity fields is straightforward. We also discuss the fate of the U(1) gauge field on the D-brane world-volume after tachyon condensation.

  1. R-symmetries, anomalies and non-invertible defects from non-BPS branes

    hep-th 2025-06 conditional novelty 6.0 of 10

    The U(1)_R symmetry operator of the Klebanov-Witten theory is realized by a non-BPS KK monopole, whose worldvolume action matches the SymTh operator and anomaly coefficients.

  2. Defrosting the Born-Infeld dyonic frozen star with tachyon matter: spectrum of oscillations

    gr-qc 2026-07 conditional novelty 5.0 of 10

    A Born-Infeld Lagrangian with electric, magnetic, and tachyon charges reproduces the slow, long-lived oscillation spectrum of the defrosted frozen star.

  3. Formation of Frozen Stars from collapsing matter by tunneling

    gr-qc 2025-08 reject novelty 5.0 of 10

    By Euclidean path-integral methods, the authors claim the tunneling probability from a collapsing shell into a frozen star is unity, making the transition inevitable.
