从一维光晶格中释放的任意子噪声关联函数研究
Noise correlations in the expansion of one-dimensional anyon gases from a regular array
摘要
Abstract
The dynamics and the noise correlations of one-dimensional anyons are investigated.Then the exact solutions are used to derive the explicit formulae of the noise correlations for both the non-interacting and interacting anyons released from a regular array.For the non-interacting anyons, interpolating between the known results of Bose and Fermi gas.For the interacting anyons, apart from the anyonic statistics, the Hamiltonian also exhibits dynamical interactions.Thus the noise correlations for the interacting anyons have a number of features that distinguish it from the non-interacting problem.A set of line-shapes appear in the noise correlations due to the distribution of scattering phases.The sign and location of the line-shape depend strongly on the interaction strength and the statistical parameter.Specially,in Tonks-Giradeau limit, the anyonic noise correlations flip the noise correlation of the non-interacting anyons due to the π phase shift in the scattering phase.关键词
