Realization of a Fermi-Hubbard optical tweezer array

BM Spar, E Guardado-Sanchez, S Chi, ZZ Yan… - Physical review …, 2022 - APS
We use lithium-6 atoms in an optical tweezer array to realize an eight-site Fermi-Hubbard
chain near half filling. We achieve single site detection by combining the tweezer array with …

A review on the application of molecular dynamics to the study of coalbed methane geology
