2 Critical Phenomena We’ll focus on a speci c example that’s very instructive: the ferromagnetic Ising Model Although it looks too speci c, it turns out that the behavior near the phase transition is the same for a lot of di erent systems, a phenomenon that looks kind of mysterious by now but will be justi ed later, known as universality
Critical exponents and transport properties near the QCD critical endpoint from the statistical bootstrap model Guruprasad Kadam 1,2,a , Hiranmaya Mishra 3,b , Marco Panero 4,5,c
of strong interactions The bootstrap model shows critical behavior near the quark-hadron transition temperature if the parameter characterizing the degeneracy of Hagedorn states is properly chosen We calculate the critical exponents and amplitudes of relevant thermodynamic quantities near the QCD critical point and combine them with an Ansatz
Rev Lett 92, 080602 s2004d; Phys Rev E 69, 061102 s2004dg In this paper we study the critical exponents near a bifurcation point for an analytically solvable case; that of a piecewise linear well with an imposed dichotomous ?uctuation It is shown how an exponent 2 emerges when a parameter is changed to move a
holds for all nearest-neighbor ferromagnetic spin models in dimension d > 2, irrespective of the single-spin measure Note, in particular, that since the GS, BFS,
