弱相互作用玻色子平均场演化的二阶修正

Second-order corrections to mean-field evolution of weakly interacting Bosons, II

M. Grillakis, M. Machedon, D. Margetis

摘要:

研究了N体弱相互作用玻色子系统的演化。我们的工作是我们以前的论文I的推广,在论文I中,我们导出了在小相互作用势存在下相干态的平均场演化律的二阶修正。在这里,我们删除的相互作用势的小的假设,并证明整体存在的二阶校正方程的解决方案。这意味着改进的福克空间估计我们的近似的N体状态。

英文摘要:

We study the evolution of a N-body weakly interacting system of Bosons. Our work forms an extension of our previous paper I, in which we derived a second-order correction to a mean-field evolution law for coherent states in the presence of small interaction potential. Here, we remove the assumption of smallness of the interaction potential and prove global existence of solutions to the equation for the second-order correction. This implies an improved Fock-space estimate for our approximation of the N-body state.
