The glass transition and the replica symmetry breaking in vortex matter
National Center for Theoretical Sciences and Electrophysics Department,National Chiao Tung University,Hsinchu 30050, Taiwan, R.O.C.(Dated: February 2, 2008)We quantitatively describe the competition between the thermal ﬂuctuations and the disorderusing the Ginzburg – Landau approach. Flux line lattice in type II superconductors undergoesa transition into three “disordered” phases: vortex liquid (not pinned), homogeneous vortex glass(pinned) and crystalline Bragg glass (pinned) due to both thermal ﬂuctuations and random quencheddisorder. We show that disordered Ginzburg – Landau model (valid not very far from H
