摘要
According to Boltzmann-Gibbs (BG) 統計 mechanics, the 熱力學 response, such as the isothermal susceptibility, at critical points (CPs) presents a divergent-like behavior. An appropriate parameter to probe both classical and 量子 CPs is the so-called Gr & uuml;neisen ratio Gamma. Motivated by the results reported in [Phys. Rev. B 108, L140403 (2023)], we extend the 量子 version of Gamma to the nonadditive q-熵 Sq. Our findings indicate that using Sq at the unique value of q restoring the extensivity of the 熵, Gamma is universally nondiverging at CPs. We unprecedentedly introduce Gamma in terms of Sq, being BG recovered for q -* 1. We thus solve a long-standing problem related to the illusory diverging susceptibilities at CPs.
