Dynamical transverse Meissner effect and transition in moving Bose glass

[摘要] We study moving periodic structures in presence of correlated disorder using renormalization group. We find that the effect of disorder persists at all velocities resulting at zero temperature in a moving Bose glass phase with transverse pinning. At nonzero temperature we find two distinct moving glass phases. We predict a sharp transition, as velocity increases between the moving Bose glass, where the transverse Meissner effect persists in the direction transverse to motion and a correlated moving glass at high velocity, where it disappears. Experimental consequences for vortex lattices and charge-density wave systems are discussed.
