We study conformations of the Gaussian polymer chains in d -dimensional space in the presence of an external field with the harmonic potential. We apply a path integral approach to derive an explicit expression for the probability distribution function of the gyration radius. We calculate this function using Monte Carlo simulations and show that our numerical and theoretical results are in a good agreement for different values of the external field.

谐波势中的高斯聚合物链:路径积分法

我们在具有谐波势的外场存在下研究d维空间中高斯聚合物链的构象。我们应用路径积分方法来为旋转半径的概率分布函数导出一个明确的表达式。我们使用蒙特卡洛模拟来计算该函数,并表明我们的数值和理论结果对于外部场的不同值具有很好的一致性。
