Flux-line entanglement as the mechanism of melting transition in high-temperature superconductors in a magnetic field

Yoshihiko Nonomura, Xiao Hu, Masashi Tachiki

The mechanism of the flux-line-lattice (FLL) melting in anisotropic high-T_c superconductors in $\mathbf{B}\parallel \hat{\mathbf{c}}$ is clarified by Monte Carlo simulations of the 3D f…
