Microscopic theory of the Hubbard interaction in low-dimensional optical lattices

Year: 2025

Type: article

Abstract: The authors provide an exact solution to the problem of two atoms interacting in quasi-one-dimensional and quasi-two-dimensional optical lattices. Based on the solution, they develop a formalism to determine the effective Hubbard on-site interaction for an optical lattice in a quantum gas microscope, which agrees with spectroscopic measurements.
