(a) The 3D plot of the Wilson ratio R χs w maps out the phase diagram of the 1D Hubbard model at low temperatures, which significantly marks different phases of states. The parameter setting reads: T = 0.005 and u = 1. (b) A plot of the Wilson ratio R χs w at fixed B = 0.4,u = 1. As the chemical potential changes, four phases (I, II, IV and V) can be reached, indicated by sudden enhancements of the Wilson ratio.

constraints are from direct searches for axion-nucleon coupling and
indirect searches for spin-dependent forces. Experiments at different
Compton frequencies corresponds to different ALP masses ma.
There are important consequences that the laboratory constraints
