标题： Sequence Dependence of Self-Interacting Random Chains

摘要： 我们研究了Iori、Marinari和Parisi提出的随机链模型的热力学行为，以及这种行为如何依赖于链上实际的相互作用序列。 随机选择的序列的性质与通过序列空间中的模拟退火过程获得的设计序列的性质进行比较。 我们表明，对于设计序列，折叠相变发生在较弱的淬火无序强度下。 因此，这些序列的折叠可以相对较快。 显示英文摘要

摘要： We study the thermodynamic behavior of the random chain model proposed by Iori, Marinari and Parisi, and how this depends on the actual sequence of interactions along the chain. The properties of randomly chosen sequences are compared to those of designed ones, obtained through a simulated annealing procedure in sequence space. We show that the transition to the folded phase takes place at a smaller strength of the quenched disorder for designed sequences. As a result, folding can be relatively fast for these sequences.
