我们讨论了混合态的II型超导体的霍尔效应，重点是附近的涡旋玻璃化转变的制度。这种转变被认为具有隐藏的“粒子-空穴对称性，并引入一个新的指数来表征粒子-空穴不对称性的无关性。这导致了一个自然的解释的缩放的霍尔和纵向磁导率在YBa{sub 2}Cu{sub 3}O{sub 7}中观察到。在过渡，非线性霍尔电压被预测为随电流的万有功率而变化，并且线性交流霍尔电导率随频率的万有功率而变化。
We discuss the Hall effect in the mixed state of type-II superconductors with an emphasis on the regime near the vortex-glass transition. This transition is argued to have a hidden'' particle-hole symmetry, and a new exponent is introduced to characterize the irrelevance of the particle-hole asymmetry. This leads to a natural explanation of the scaling of the Hall and Longitudinal resistivities observed in YBa{sub 2}Cu{sub 3}O{sub 7}. At the transition, the nonlinear Hall voltage is predicted to vary with a universal power of the current, and the linear ac Hall conductivity with a universal power of the frequency.
