【 摘 要 】
We study the spectrum of the states localized in the. vortex:cores in die mixed state of clean layered superconductors. S-wave coupling is assumed. It is found that in a large region of parameters adjacent to the superclean case a universal (i.e., independent of the density of impurities) class of level statistics arises. It is the circular unitary random matrix ensemble. The density of:states fur such conditions is calculated. The absorption resulting from the Landau-Zener transitions between these levels is different from the classical result for an isotropic three-dimensional system. [S0163-1829(99)03242-7].
