Query: Interaction-induced Bose Metal in 2D   We show here that the regularization of the conductivity resulting from the
bosonic interactions on the `insulating' (quantum disordered) side of an
insulator-superconductor transition in 2D gives rise to a metal with a finite
conductivity, $\sigma =(2/\pi) 4 e^2/h$, as temperature tends to zero. The Bose
metal is stable to weak disorder and hence represents a concrete example of an
interaction-induced metallic phase. Phenomenological inclusion of dissipation
reinstates the anticipated insulating behaviour in the quantum-disordered
regime. Hence, we conclude that the traditionally-studied
insulator-superconductor transition, which is driven solely by quantum
fluctuations, corresponds to a superconductor-metal transition. The possible
relationship to experiments on superconducting thin films in which a
low-temperature metallic phase has been observed is discussed.
