摘要翻译:
Jarzynski非平衡功关系在自由能计算中的应用由于耗散较大时估计的收敛速度很慢而受到限制。本文提出了一种新的扰动协议,该协议能够改善Jarzynski估计在平均力势重构中的收敛性。改进的基础是除热波动引起的外功变化外,还应用了自适应外功变化。

英文摘要:
Application of Jarzynski nonequilibrium work relation to free energy calculation is limited by the very slow convergence of the estimate when dissipation is high. We present a novel perturbation protocol able to improve the convergence of Jarzynski estimator when it is applied in the reconstruction of the potential of mean force. The improvement is based on the application of the adaptive external work variation in addition to the one caused by thermal fluctuations.
