摘要: We discuss the Hall effect in mixed state of type-II superconductors with an emphasis on regime near vortex-glass transition. This transition is argued to have a hidden'' particle-hole symmetry, and new exponent introduced characterize irrelevance asymmetry. leads natural explanation scaling Longitudinal resistivities observed YBa{sub 2}Cu{sub 3}O{sub 7}. At transition, nonlinear voltage predicted vary universal power current, linear ac conductivity frequency.
