Zero temperature correlation functions for the impenetrable fermion gas | | Vadim V Cheianov

21 Oct 2003 | | Journal: | J. Phys. A: Math. Gen. vol. 37 (2004) 2261-2297 | | Subject: | Strongly Correlated Electrons; Statistical Mechanics; Mathematical Physics | cond-mat.str-el cond-mat.stat-mech math-ph math.MP | | Abstract: | We calculate the long time and distance asymptotics of the one-particle correlation functions in the model of impenetrable spin 1/2 fermions in 1+1 dimensions. We consider the spin disordered zero temperature regime, which occurs when the limit $T o0$ is taken at a positive chemical potential. The asymptotic expressions are found from the asymptotic solution of the matrix Riemann-Hilbert problem related to the determinant representation of the correlation functions. | | Source: | arXiv, cond-mat/0310499 | | Services: | Forum | Review | PDF | Favorites | |
