We study the response of a rotating BTZ black hole to the scalar tidal perturbation. We show that the real component of the tidal response function isn't zero, indicating that a rotating BTZ black hole possesses non-zero tidal Love numbers. Additionally, we observe scale-dependent behaviour, known as log-running, in the tidal response function. We also conduct a separate analysis on an extremal rotating BTZ black hole, finding qualitative similarities with its non-extremal counterpart. In addition, we present a procedure to calculate the tidal response function of a charged rotating BTZ black hole as well.

  1. The Ringdown and the Tide: Fingerprints of Dark Matter Halo Profiles

    gr-qc 2026-08 conditional novelty 6.0 of 10

    For black holes in generalized (alpha,beta,gamma) dark matter halos, the axial ringdown shift is set by a single redshift integral, while the tidal Love number depends on an outer radial moment, making the two observa...

  2. Love Numbers for Extremal Kerr Black Hole

    hep-th 2024-12 conditional novelty 6.0 of 10

    Extremal Kerr black holes have finite static and low-frequency dynamical tidal Love numbers, with dissipative parts that do not vanish.

  3. Tidal deformation of an accreting compact object

    gr-qc 2026-07 conditional novelty 5.0 of 10

    For perfectly reflecting Schwarzschild-like ECOs, the log-compactness scaling of static scalar and spin-1 Love numbers survives a thin accretion disk, which mainly amplifies the response magnitude.

  4. Can wormholes have vanishing Love numbers?

    gr-qc 2026-05 unverdicted novelty 5.0 of 10

    The paper claims the ℓ=2 magnetic tidal Love number of the Dadhich–Kar–Mukherji–Visser R=0 wormhole vanishes to first order in the regularization parameter p, based on a throat-regularity condition that removes the 1/...
