In this paper, we have discussed the effects of quantum fluctuations spewed by a black hole on its deflection angle. The Gauss-Bonnet theorem (GBT) is exploited with quantum corrections through the Extended Uncertainty Principle (EUP) and the corresponding deflection angle is obtained. Moreover, we have attempted to broaden the scope of our work by subsuming the effects of plasma medium on the deflection angle as well. To demonstrate the degree of difference, the acquired results are compared with the prevailing findings.

  1. Extended uncertainty principle inspired black hole in a G\"odel Universe

    gr-qc 2025-05 reject novelty 4.0 of 10

    A Godel-rotation-modified uncertainty principle is used to define a corrected black hole mass, producing enlarged horizon, shadow, and deflection with lower bounds a/M ~ 10^5 from EHT and PPN data.

  2. Effect of the hair on deflection angle by asymptotically flat black holes in Einstein-Maxwell-dilaton theory

    gr-qc 2019-08 conditional novelty 4.0 of 10

    The paper derives explicit weak-field deflection formulas, including plasma corrections, for hairy black holes in Einstein-Maxwell-dilaton theory, with hair encoded through a dilaton potential parameter alpha.

  3. Spacetime-curvature induced uncertainty principle: linking the large-structure global effects to the local black hole physics

    gr-qc 2024-11 reject novelty 3.0 of 10

    The authors derive a black hole metric with a cosmological-constant-dependent effective mass and use EHT and VLBI data to put extremely weak bounds on a quantum parameter beta.
