It is observed that many thin superconducting films with not too high disorder level (generally R_N/≤ 2000 Ω) placed in magnetic field show an anomalous metallic phase where the resistance is low but still finite as temperature goes to zero. Here we report in weakly disordered amorphous InO_x thin films, that this "Bose metal" metal phase possesses no cyclotron resonance and hence non-Drude electrodynamics. Its microwave dynamical conductivity shows signatures of remaining short-rangedoi:10.1103/physrevlett.120.167002 pmid:29756920 fatcat:55xp62ttcbgazfxg3r3quscxju
