访问晶格聚合物和蛋白质的低温热力学的通用方法

Versatile approach to access the low temperature thermodynamics of lattice polymers and proteins

Thomas Wüst, David P. Landau

摘要:

我们表明,王朗道采样,结合适当的Monte Carlo试验移动,提供了一个强大的方法,为基态搜索和确定的疏水极性(HP)蛋白质模型和相互作用的自回避行走(ISAW)模型的均聚物的态密度。我们获得了具有$>100$单体的HP序列以及高达$>500$单体的ISAW的热力学量的准确估计。我们的程序具有内在的简单性,并克服了更定制的方法中固有的局限性,使其对广泛的蛋白质和聚合物模型感兴趣。

英文摘要:

We show that Wang-Landau sampling, combined with suitable Monte Carlo trial moves, provides a powerful method for both the ground state search and the determination of the density of states for the hydrophobic-polar (HP) protein model and the interacting self-avoiding walk (ISAW) model for homopolymers. We obtained accurate estimates of thermodynamic quantities for HP sequences with $>100$ monomers and for ISAWs up to $>500$ monomers. Our procedure possesses an intrinsic simplicity and overcomes the limitations inherent in more tailored approaches making it interesting for a broad range of protein and polymer models.
