WebIn statistical mechanics, the Griffiths inequality, sometimes also called Griffiths–Kelly–Sherman inequality or GKS inequality, named after Robert B. Griffiths, is a correlation inequality for ferromagnetic spin systems. Informally, it says that in ferromagnetic spin systems, if the 'a-priori distribution' of the spin is invariant under spin flipping, the …
WebAug 30, 2013 · Griffiths phases and the stretching of criticality in brain networks. Hallmarks of criticality, such as power-laws and scale invariance, have been empirically found in cortical networks and it has been conjectured that operating at criticality entails functional advantages, such as optimal computational capabilities, memory, and large … WebJun 29, 2024 · In the Griffiths phase region, the finite size FiM clusters exist but no static long-range order is developed. Therefore, spontaneous magnetization is zero in the Griffiths region. Hence, it is obvious from figure 5 that the region above T C is not a purely paramagnetic phase, but it is a Griffiths region.
