  We discuss whether a simple theory of superconducting stripes coupled by
Josephson tunneling can describe a metallic transport, once the coherent
tunneling of pairs is suppressed by the magnetic field. For a clean system, the
conclusion we reached is negative: the excitation spectrum of preformed pairs
consists of Landau levels, and once the magnetic field exceeds a critical
value, the transport becomes insulating. As a speculation, we suggest that a
Bose metal can exist in disordered systems provided that the disorder is strong
enough to localize some pairs. Then the coupling between propagating and
localized pairs broadens the Landau levels, resulting in a metallic
conductivity. Our model respects the particle-hole symmetry, which leads to a
zero Hall response. And intriguingly, the resulting anomalous metallic state
has no Drude peak and the spectral weight of the cyclotron resonance vanishes
at low temperatures.
