非线性量子行走的散射和逆散射

Scattering and inverse scattering for nonlinear quantum walks

Masaya Maeda, Hironobu Sasaki, Etsuo Segawa, Akito Suzuki, Kanako Suzuki

摘要:

研究了具有自相关(非线性)硬币的量子行走的大时间行为。特别是,我们展示了散射,并推导出再现公式逆散射弱非线性制度。证明是基于(线性)量子阱的时空估计,如色散估计和Eschenhartz估计。这种论证在非线性薛定谔方程和离散非线性薛定谔方程的研究中是标准的,但它似乎是第一次被应用于量子阱。

英文摘要:

We study large time behavior of quantum walks (QWs) with self-dependent (nonlinear) coin. In particular, we show scattering and derive the reproducing formula for inverse scattering in the weak nonlinear regime. The proof is based on space-time estimate of (linear) QWs such as dispersive estimates and Strichartz estimate. Such argument is standard in the study of nonlinear Schrödinger equations and discrete nonlinear Schrödinger equations but it seems to be the first time to be applied to QW.
