Long-Range Self-Affine Correlations in a Random Soliton Gas

Guerrero, Luis, López, Eduardo and González, Jorge (1997) Long-Range Self-Affine Correlations in a Random Soliton Gas. Physical Review E (Statistical, Nonlinear, and Soft Matter Physics), 55 (6). pp. 7691-7695.


The random sine-Gordon chain experiences a sharp crossover to an ordered state associated with the activation of a soliton gas. The spatial coherence of the stationary regimes has three well-defined scaling behaviors. At larger scales there is no correlation, reflecting the independence between the different local structures in the chain. In this paper we introduce a different potential that produces solitons that exhibit long-range interactions. We show that a gas of such solitons can extend self-affinity to all scales.
