摘要:
本文提出了一种计算二维晶格中Wannier-Stark共振态的简单方法。利用这种方法计算了光晶格中不可分二维势的复Wannier-Stark谱,并分析了它的一般结构.简要讨论了静态场方向(相对于晶格晶轴)对Wannier-Stark态寿命的影响。
英文摘要:
A simple method of calculating the Wannier-Stark resonances in 2D lattices is suggested. Using this method we calculate the complex Wannier-Stark spectrum for a non-separable 2D potential realized in optical lattices and analyze its general structure. The dependence of the lifetime of Wannier-Stark states on the direction of the static field (relative to the crystallographic axis of the lattice) is briefly discussed.
