When we consider charged AdS black holes in higher dimensional spacetime and a molecule number density along coexistence curves is numerically extended to higher dimensional cases. It is found that a number density difference of a small and large black holes decrease as a total dimension grows up. In particular, we find that a configurational entropy is a concave function of a reduced temperature and reaches a maximum value at a critical (second-order phase transition) point. Furthermore, the bigger a total dimension becomes, the more concave function in a configurational entropy while the more convex function in a reduced pressure.

  1. Cosmological comoving behavior of the configurational entropy

    gr-qc 2019-08 reject novelty 5.0 of 10

    The paper claims the configurational entropy of cosmic fluids scales as a^{-3} for radiation and a^{-3/2} for matter, but the radiation result conflicts with the scale invariance of a blackbody spectrum.

    In a tachyonic braneworld, configurational entropy has a minimum at a critical scale-factor rate for AdS or flat bulk, and the paper suggests this rate sets cosmic acceleration or inflation, though the physical link i...

  3. Aspects of the Black Hole Interior Volume and Entropy

    gr-qc 2025-09 unverdicted novelty 2.0 of 10

    A doctoral thesis compiles and reproduces prior semiclassical results claiming the interior scalar-mode entropy of black holes is proportional to horizon entropy with a coefficient less than one.
