Figure 2From: Magnetic ordering of nitrogen-vacancy centers in diamond via resonator-mediated coupling Free energy landscapes of the long-range Ising model. (a) The free energy as a function of the spin polarization along the x direction at high temperature \(\tilde{\beta}\equiv NJ/k_{B}T=0.5\). (b) The same as (a) but at a lower temperature \(\tilde {\beta}\equiv NJ/k_{B}T=2.0\).Back to article page
