Momentum distribution (IMAGE)
Caption
(a) Small momentum region, n(k) ∝kα. The black dashed lines show the fitted slopes α of -0.750 (γ = 4.0) and -0.908 (γ = 0.5), which are in agreement with the theoretical predictions of linear Luttinger liquid -0.737 and -0.894. (b) Large momentum region, n(k) ∝ k-4. The black dashed lines display the fitted slopes of -4.073 (γ = 4.0) and -4.001 (γ = 0.5), perfectly conforming to the universal law of the interacting systems - Tan's Contact.
