AB It is generally expected that when a magnetic field destroys superconductivity in two dimensions, the system becomes an insulator. It is shown that there is a type of superconductivity—namely, the one where the wave function of pairs is odd in time—where the result is not an insulator, but a metal with a zero Hall response. It is suggested that the transition recently observed in the striped-ordered high-Tc superconductor La1.875Ba0.125CuO4 may belong to this category.It is shown that the application of a sufficiently strong magnetic field to the odd-frequency–paired pair-density wave state described in A. M. Tsvelik [Phys. Rev. B 94, 165114 (2016)] leads to formation of a low-temperature metallic state with zero Hall response. Applications of these ideas to the recent experiments on stripe-ordered La1.875Ba0.125CuO4 (LBCO) are discussed.
