Generalized Bloch oscillations of ultracold lattice atoms subject to higher-order gradients
Qian-Ru Zhu, Shou-Long Chen, Shao-Jun Li +3
The standard Bloch oscillation normally refers to the oscillatory tunneling dynamics of quantum particles in a periodic lattice plus a linear gradient. In this work we theoreticall…

Nanoscale angular lattice formed by light with high orbital angular
Zheng Li, Xiang Gao, Lushuai Cao
Standing waves generated by the interference of Laguerre-Gaussian (LG) beams can be used for dipole trap. We propose a scheme to create a nanometer (nm) scale ring lattice based on…
