Betatron emission from relativistic electrons in a high intensity optical lattice
Physical Review Special Topics. Accelerators and Beams, 2013 We describe theoretically and numerically the interaction of a laser- or LINAC-accelerated beam of relativistic electrons with a high intensity optical lattice, resulting from the superposition of two transverse laser pulses.

Femtosecond Laser Induced Lattice Deformation in KTN Crystal
Micromachines, 2022 In recent years, many novel optical phenomena have been discovered based on perovskite materials, but the practical applications are limited because of the difficulties of device fabrication. Here, we propose a method to directly induce localized lattice

Landau damping of Bogoliubov excitations in optical lattices at finite temperature
, 2005 We study the damping of Bogoliubov excitations in an optical lattice at finite temperatures. For simplicity, we consider a Bose-Hubbard tight-binding model and limit our analysis to the lowest excitation band.

Journal of Applied Mathematics, 2014 We modified the spectral renormalization method as the pseudospectral renormalization method in order to find the localized solutions. The pseudospectral renormalization method can be applied to a large class of problems including different homogeneities.

Vortex-lattice melting in a one-dimensional optical lattice
, 2006 We investigate quantum fluctuations of a vortex lattice in a one-dimensional optical lattice. Our method gives full access to all the modes of the vortex lattice and we discuss in particular the Bloch bands of the Tkachenko modes.

Phase separation of binary condensates in harmonic and lattice potentials
, 2010 We propose a modified Gaussian ansatz to study binary condensates, trapped in harmonic and optical lattice potentials, both in miscible and immiscible domains.

Recent Advances Concerning the 87Sr Optical Lattice Clock at the National Time Service Center
Applied Sciences, 2018 We review recent experimental progress concerning the 87Sr optical lattice clock at the National Time Service Center in China. Hertz-level spectroscopy of the 87Sr clock transition for the optical lattice clock was performed, and closed-loop operation of
