Long-range critical exponents near the short-range crossover
The d-dimensional long-range Ising model, defined by spin-spin interactions decaying with the distance as the power 1/rd+s, admits a second-order phase transition with continuously varying critical exponents. At s=s*, the phase transition crosses over to the usual short-range universality class. The...
