我们表明，聚合物的塌缩球状相适应其接触的无标度不相容图。发现该网络的度分布随指数γ=1/(2-c)衰减，直至截止度dc与L(2-c)成正比，其中是致密聚合物的环指数(二维c=11/8)，是聚合物的长度。我们的结果举例说明了无标度网络是如何走出标准临界点的。
We show that the collapsed globular phase of a polymer accommodates a scale-free incompatibility graph of its contacts. The degree distribution of this network is found to decay with the exponent gamma=1/(2-c) up to a cutoff degree dc proportional to L(2-c), where is the loop exponent for dense polymers (c=11/8 in two dimensions) and is the length of the polymer. Our results exemplify how a scale-free network can emerge from standard criticality.
