稀释无序聚合物模型的猝灭临界点

The quenched critical point of a diluted disordered polymer model

Erwin Bolthausen, Francesco Caravenna, Béatrice de Tilière

摘要:

我们考虑一个模型的聚合物相互作用的吸引力墙通过一个随机序列的电荷。我们专注于所谓的稀释极限,当电荷非常罕见,但具有很强的强度。在这个制度下,我们确定淬火临界点的模型,表明它是不同的退火。证明是基于严格的重整化过程。应用我们的结果的选择性界面附近的共聚物的问题进行了讨论。

英文摘要:

We consider a model for a polymer interacting with an attractive wall through a random sequence of charges. We focus on the so-called diluted limit, when the charges are very rare but have strong intensity. In this regime, we determine the quenched critical point of the model, showing that it is different from the annealed one. The proof is based on a rigorous renormalization procedure. Applications of our results to the problem of a copolymer near a selective interface are discussed.
