The Hamilton–Jacobi tunneling method yields the Hawking temperature and its GUP-modified form, revealing how Planck-scale effects suppress thermal radiation. Exponential corrections to the Bekenstein-Hawking entropy lead to modified expressions for internal energy, Helmholtz and Gibbs free energies, pressure, enthalpy, and heat capacity. The AdS radius ℓ emerges as a critical parameter: smaller values enhance gravitational confinement and thermodynamic stability, while larger values weaken these effects. The heat capacity remains positive across parameter space, ruling out second-order phase transitions. However, the JT coefficient exhibits remarkable oscillatory behavior near <em>r_h</em> ≈ 1.05, alternating between heating and cooling phases during isenthalpic expansion. These oscillations intensify with increasing ℓ, indicating reduced stability in weakly curved AdS backgrounds. Gravitational redshift calculations in the weak-field limit show that the logarithmic charge coupling produces unbounded growth at large distances, with strong ℓ-dependence providing observational signatures. Our results demonstrate that (2+1)-dimensional black holes possess richer thermodynamic structure than their higher-dimensional counterparts, with quantum corrections introducing novel critical phenomena while preserving overall stability.

By employing Noether’s second theorem, we present an alternative formulation of the Lagrangian, which can elucidate the role of conical singularities. We demonstrate that, in general, the contribution from conical singularities depends on the specific implementation of the regularization scheme and is not uniquely determined; this feature is explicitly exhibited and confirmed in three-dimensional new massive gravity. Nevertheless, these ambiguities can be absorbed into the second-order (and higher) corrections induced by conical singularities when the gravitational theory is described by the Lagrangian <em>L</em>(<em>g_ab, R_abcd</em>). Moreover, for certain theories such as general relativity and Bumblebee gravity, this contribution simplifies to a well-defined result.
