标题： Longitudinal Current Dissipation in Bose-glass Superconductors

摘要： 一种关于电流与磁场和柱状缺陷的共同方向平行的玻色玻璃超导体中涡旋运动的标度理论被提出。 在玻色玻璃相变之上，纵向直流电阻率$\rho_{||}(T)\sim (T-T_{BG})^{\nu' z'}$比相应的横向电阻率$\rho_{\perp}(T)\sim (T-T_{BG})^{\nu' (z'-2)}$衰减得快得多，因此{\it 反转}了层状超导体正常态中通常的电输运各向异性。 在存在电流$\bf J$与公共场和柱状缺陷轴成角度$\theta_J$的情况下，电场角度$\theta_E$随着$T\rightarrow T_{BG}^+$趋近于$\pi/2$。 缩放也预测了交流电流的穿透深度行为，如$T\rightarrow T_{BG}^-$所示，并意味着在超流体密度中，沿柱状结构平行传输时，在$T_{BG}$处有一个{\it 跳跃间断点}。 显示英文摘要

摘要： A scaling theory of vortex motion in Bose glass superconductors with currents parallel to the common direction of the magnetic field and columnar defects is presented. Above the Bose-glass transition the longitudinal DC resistivity $\rho_{||}(T)\sim (T-T_{BG})^{\nu' z'}$ vanishes much faster than the corresponding transverse resistivity $\rho_{\perp}(T)\sim (T-T_{BG})^{\nu' (z'-2)}$, thus {\it reversing} the usual anisotropy of electrical transport in the normal state of layered superconductors. In the presence of a current $\bf J$ at an angle $\theta_J$ with the common field and columnar defect axis, the electric field angle $\theta_E$ approaches $\pi/2$ as $T\rightarrow T_{BG}^+$. Scaling also predicts the behavior of penetration depths for the AC currents as $T\rightarrow T_{BG}^-$, and implies a {\it jump discontinuity} at $T_{BG}$ in the superfluid density describing transport parallel to the columns.
