Quantum tunneling of flux lines in superconductors

We discuss the different regimes which can be expected for quantum creep of flux lines by analysing the experimental results obtained for the relaxation rate as T→0 for Y1Ba2Cu3O7, Bi2Sr2Ca1Cu2O8 and (ET)2Cu(NCN)2Br single crystals. We address the dimensionality of the pinned flux line, the possible bundle regime at high fields for the organic superconductor and the relative invariability of the quantum rate upon introduction of columnar defects.
