Abstract

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 [<i>Phys. Rev. B</i> 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 La<sub>1.875</sub>Ba<sub>0.125</sub>CuO<sub>4</sub> (LBCO) are discussed.
