摘要：

We study weak itinerant ferromagnetism in one-dimensional Fermi systems using perturbation theory and bosonization. We find that longitudinal spin fluctuations propagate ballistically with velocity v(m)<<v(F), where v(F) is the Fermi velocity. This leads to a large anomalous dimension in the spin channel and strong algebraic singularities in the single-particle spectral function and in the transverse structure factor for momentum transfers q approximate to 2Delta/v(F), where 2Delta is the exchange splitting.
