Review Title: Serious flaw

Review:

This article contains a serious flaw. It writes down the wavefunction for a Type II superconductor with a vortex lattice as an expansion in Landau levels - the ground state is the Abrikosov wavefunction, and the excited states include Hermite polynomials periodic along some axis. The flaw is that while the higher Landau level states do exhibit translational symmetry, they fail to exhibit (in any way) the 6-fold rotational symmetry of the vortex lattice in its equilibrium configuration - check it out with Mathematica. In actuality, with this wavefunction including higher Landau levels, the new equilibrium lattice configuration is not a perfect triangular lattice!!!!

Article Title and Code: Quantum Melting and Absence of Bose-Einstein Condensation in Two-Dimensional Vortex Matter,oai:arXiv.org:cond-mat/0201020

Review Title:

Review:

This is an interesting paper that uses field theoretic methods to describe a rapidly rotating BEC in two dimensions. While the some results of this paper agree with alternative treatments, this paper is rather abstruse and skips over many details.
