Figure 1From: Nonlinearity and nonclassicality in a nanomechanical resonator The Duffing potential. In the top panel we show \(V(x)\) for \(\varepsilon=0.2\) (red), \(\varepsilon=0.5\) (green), \(\varepsilon=0.8\) (blue). In the bottom panel we show the corresponding GS probability densities, \(|\psi_{0}|^{2}(x)\).Back to article page
