Bosonization of non-relativstic fermions in 2-dimensions and collective field theory

  title={Bosonization of non-relativstic fermions in 2-dimensions and collective field theory},
  author={Avinash Dhar},
We revisit bosonization of non-relativistic fermions in one space dimension. Our motivation is the recent work on bubbling half-BPS geometries by Lin, Lunin and Maldacena (hep-th/0409174). After reviewing earlier work on exact bosonization in terms of a noncommutative theory, we derive an action for the collective field which lives on the droplet boundaries in the classical limit. Our action is manifestly invariant under time-dependent reparametrizations of the boundary. We show that, in an… CONTINUE READING
