Ground-state properties of hard core bosons in one-dimensional harmonic traps | T. Papenbrock
; | Date: |
12 Sep 2002 | Journal: | Phys. Rev. A 67 (2003) 041601(R) DOI: 10.1103/PhysRevA.67.041601 | Subject: | Soft Condensed Matter; Statistical Mechanics | cond-mat.soft cond-mat.stat-mech | Affiliation: | Oak Ridge National Laboratory | Abstract: | The one-particle density matrices for hard core bosons in a one-dimensional harmonic trap are computed numerically for systems with up to 160 bosons. Diagonalization of the density matrix shows that the many-body ground state is not Bose-Einstein condensed. The ground state occupation, the amplitude of the lowest natural orbital, and the zero momentum peak height scale as powers of the particle number, and the corresponding exponents are related to each other. Close to its diagonal, the density matrix for hard core bosons is similar to the one of noninteracting fermions. | Source: | arXiv, cond-mat/0209300 | Services: | Forum | Review | PDF | Favorites |
