范德瓦尔斯力的重整化和普适性

Renormalization and Universality of Van der Waals forces

E. Ruiz Arriola, A. Calle Cordon

摘要:

重整化思想与边界条件的叠加原理相结合,可以有效地描述中性原子间奇异和长程范德华力的模型无关和普适标度特性。主导的幂律的主导地位是突出的散射以及在束缚态问题。从普适性和低能标度的角度分析了在有效场论框架下离壳两体么正性和因果性的作用。

英文摘要:

Renormalization ideas can profitably be exploited in conjunction with the superposition principle of boundary conditions in the description of model independent and universal scaling features of the singular and long range Van der Waals force between neutral atoms. The dominance of the leading power law is highlighted both in the scattering as well as in the bound state problem. The role of off-shell two-body unitarity and causality within the Effective Field Theory framework on the light of universality and scaling at low energies is analyzed.
