Accordion lattice based on the Talbot effect

Abstract

We introduce an idea of producing an optical lattice relied on the Talbot effect. Our alternative scheme is based on the interference of light behind a diffraction grating in the near-field regime. We demonstrate 1-D and 2-D optical lattices with the simulations and experiments. This Talbot optical lattice can be broadly used from quantum simulations to quantum information. The Talbot effect is usually used in lensless optical systems, therefore it provides small aberrations.

Spin dynamics of high-spin fermions in optical superlattices

“…Fermionic atoms with high spin (s > 1∕2) in optical lattices [1][2][3][4] provide a powerful and controllable platform for developing physical systems that go beyond the traditional spin 1∕2 magnetism and for enabling an understanding of fundamental spin-spin interactions [5][6][7][8][9] . Widespread attention has been paid to the exploration of spin-changing collisions [10][11][12][13][14] , the realization of exotic quantum phases [15][16][17][18][19][20][21] , and the simulation of SU(N ) magnetism [22][23][24][25][26][27] .…”
