9412672这个更新的建议将集中在第二类超导体的输运性质使用广义半经典方法，并将开发玻色化方法来研究强关联系统。 研究高温超导体输运性质的动机是为了了解高温超导体中的反常电阻特性。 玻色化方法是研究非费米液体基态奇异性质的一种非微扰方法。 该方法适用于大于1的尺寸。 本论文的主要工作是利用广义半经典方法和玻色化方法研究强关联系统。 半经典方法将被用来研究磁场中的第二类超导体的输运性质的动机解释异常的电阻特性。 玻色化方法将有助于更好地理解强关联系统复杂的基态性质。

9412672 This renewal proposal will focus on transport properties of type II superconductors using generalized semiclassical methods and will develop bosonization approach to study strongly correlated systems. The motivation for the study of transport properties is to understand the anomalous resistive characteristics in high temperature superconductors. The bosonization approach is a nonperturbative way to study exotic properties of non-Fermi liquid ground states. The method is applicable to dimensions greater than one. %%% The proposed work will be to study strongly correlated systems using generalized semiclassical methods and bosonization approach. Semiclassical methods will be used to study transport properties of type II superconductors in magnetic field with the motivation to explain anomalous resistive characteristics. Bosonization method will provide better understanding of the complicated ground state properties of strongly correlated systems.
