Spin and Charge Luttinger-Liquid Parameters of the One-Dimensional Electron Gas
arXiv:cond-mat/0005354 · doi:10.1209/epl/i2001-00140-7
Abstract
Low-energy properties of the homogeneous electron gas in one dimension are completely described by the group velocities of its charge (plasmon) and spin collective excitations. Because of the long range of the electron-electron interaction, the plasmon velocity is dominated by an electrostatic contribution and can be estimated accurately. In this Letter we report on Quantum Monte Carlo simulations which demonstrate that the spin velocity is substantially decreased by interactions in semiconductor quantum wire realizations of the one-dimensional electron liquid.
