标题： Renormalization group approach to vibrational energy transfer in protein

摘要： 重整化群方法被应用于研究蛋白质分子中的振动能量转移。 通过已发展成为全局渐近分析统一工具的一阶微扰重整化群理论，分析了描述共振能量转移的有效拉格朗日量和相应的运动方程。 在消除了与费米共振相关的奇异项后，推导出描述振动能量转移缓慢动力学的振幅方程，这些方程恢复了非线性光学中开发的技术所得结果 [S.J. Lade, Y.S. Kivshar, Phys. Lett. A 372 (2008) 1077]。 显示英文摘要

摘要： Renormalization group method is applied to the study of vibrational energy transfer in protein molecule. An effective Lagrangian and associated equations of motion to describe the resonant energy transfer are analyzed in terms of the first-order perturbative renormalization group theory that has been developed as a unified tool for global asymptotic analysis. After the elimination of singular terms associated with the Fermi resonance, amplitude equations to describe the slow dynamics of vibrational energy transfer are derived, which recover the result obtained by a technique developed in nonlinear optics [S.J. Lade, Y.S. Kivshar, Phys. Lett. A 372 (2008) 1077].
