Field theories with spontaneous Lorentz violation involving an antisymmetric 2-tensor are studied. A general action including nonminimal gravitational couplings is constructed, and features of the Nambu-Goldstone and massive modes are discussed. Minimal models in Minkowski spacetime exhibit dualities with Lorentz-violating vector and scalar theories. The post-newtonian expansion for nonminimal models in Riemann spacetime involves qualitatively new features, including the absence of an isotropic limit. Certain interactions producing stable Lorentz-violating theories in Minkowski spacetime solve the renormalization-group equations in the tadpole approximation.

  1. Black Hole Entropy Beyond the Wald Term in Nonminimally Coupled Gravity: A Covariant Phase Space Decomposition

    gr-qc 2026-05 unverdicted novelty 6.0

    Black hole entropy in diffeomorphism-invariant nonminimal gravity decomposes as S_H = S_W + S_1 + ΔS, with the extra terms required for bumblebee and Weyl-vector Gauss-Bonnet solutions but not for regular Kalb-Ramond ...

  2. Revisiting black holes and their thermodynamics in Einstein-Kalb-Ramond gravity

    gr-qc 2025-11 unverdicted novelty 5.0

    Exact black hole solutions with topological horizons are found in EKR gravity and their thermodynamics are analyzed using the Wald formalism for mass and entropy.

  3. Validity of the Background Subtraction Method for Black Hole Thermodynamics in Matter-Coupled Gravity Theories

    gr-qc 2025-11 unverdicted novelty 5.0

    Background subtraction for black hole thermodynamics is valid and equivalent to Iyer-Wald in matter-coupled gravity theories, with smooth performance in examples but subtleties for certain matter fields.

  4. Gravitational Wave Birefringence from Fuzzy Dark Matter

    gr-qc 2024-06 unverdicted novelty 5.0

    Fuzzy dark matter induces frequency-dependent amplitude birefringence in gravitational waves with periodic time modulation set by the scalar mass, but no velocity birefringence.

  5. Scattering, absorption and greybody factor of scalar particles by Lorentz-violating charged black holes

    gr-qc 2026-05 unverdicted novelty 4.0

    Partial-wave calculations of scattering cross sections, absorption, and greybody factors for spin-0 particles on charged black holes in bumblebee and Kalb-Ramond Lorentz-violating models.

  6. Probing Kalb-Ramond gravity with charged rotating black holes: constraints from EHT observations

    gr-qc 2026-04 unverdicted novelty 3.0

    EHT shadow observations constrain the Lorentz-violating parameter ℓ in Kalb-Ramond gravity for charged rotating black holes to roughly |ℓ| ≲ 0.1-0.2, with an upper bound ℓ ≲ 0.19 from Sgr A*.
