abstract

In $U(1)$ gauge-invariant scalar-vector-tensor theories with second-order equations of motion, we study the properties of black holes (BH) on a static and spherically symmetric background. In shift-symmetric theories invariant under the shift of scalar $\phi \to \phi+c$, we show the existence of new hairy BH solutions where a cubic-order scalar-vector interaction gives rise to a scalar hair manifesting itself around the event horizon. In the presence of a quartic-order interaction besides the cubic coupling, there are also regular BH solutions endowed with scalar and vector hairs.

  1. Spontaneous scalarization of charged black holes in the Scalar-Vector-Tensor theory

    gr-qc 2019-08 conditional novelty 6.0 of 10

    Spontaneous scalarization of Reissner-Nordström black holes occurs in the scalar-vector-tensor f4 model, and the resulting scalarized black holes can be overcharged.

  2. Radial Oscillations of Neutron Stars with Vector-Induced Scalar Hair

    gr-qc 2026-02 unverdicted novelty 5.0 of 10

    In scalar-vector-tensor gravity, the vector-curvature coupling alters neutron star mass-radius curves and radial oscillation frequencies while preserving the coincidence of maximum mass with the onset of radial instability.

  3. Noncanonical Approaches To Inflation

    gr-qc 2019-06 unverdicted novelty 3.0 of 10

    A review thesis covering Mukhanov parametrization, general scalar-tensor theories, and new slow-roll techniques for canonical and noncanonical inflation observables.
