Query: Bose Metal as a Disruption of the Berezinskii-Kosterlitz-Thouless
  Transition in 2D Superconductors   Destruction of superconductivity in thin films was thought to be a simple
instance of Berezinskii-Kosterlitz-Thouless physics in which only two phases
exist: a superconductor with algebraic long range order in which the vortices
condense and an insulator where the vortex-antivortex pairs proliferate.
However, since 1989 this view has been challenged as now a preponderance of
experiments indicate that an intervening bosonic metallic state obtains upon
the destruction of superconductivity. We review here a glassy model which is
capable of capturing both of these features. The finite resistance arises from
three features. First, the disordered insulator-superconductor transition in
the absence of fermionic degrees of freedom (Cooper pairs only), is controlled
by a diffusive fixed point\cite{CN} rather than the critical point of the clean
system. Hence, the relevant physics that generates the Bose metal should arise
from a term in the action in which different replicas are mixed. We show
explicitly how such physics arises in the phase glass. Second, in 2D (not in
3D) the phase stiffness of the glass phase vanishes explicitly as has been
shown in extensive numerical simulations\cite{ky,kosterlitz1,kosterlitz2}.
Third, bosons moving in such a glassy environment fail to localize as a result
of the false minima in the landscape. We calculate the conductivity explicitly
using Kubo response and show that it turns on as a power law and has a
vanishing Hall response as a result of underlying particle-hole symmetry. We
show that when particle-hole symmetry is broken, the Hall conductance turns on
with the same power law as does the longitudinal conductance.
