英文摘要We present a rigorous study of momentum distribution and p-wave contacts of one-dimensional spinless Fermi gases with an attractive p-wave interaction. Using the Bethe ansatz wave function, we calculate analytically the high-momentum tail and show that the leading (similar to 1/p(2)) and sub-leading terms (similar to 1/p(4)) are determined by two contacts C-2 and C-4, which are related to the short-distance behavior of the two-body density matrix and its derivatives. As one increases the one-dimensional scattering length, the contact C-2 increases monotonically from zero while C-4 exhibits a peak at finite scattering length. In addition, we obtain analytic expressions for p-wave contacts at finite temperature from the thermodynamic Bethe ansatz equations for both weak and strong attractive interactions.
