磁场作用下的准周期镶嵌

Quasiperiodic tilings under magnetic field

J. Vidal, R. Mosseri

摘要:

研究了二维准周期镶嵌--等距广义Rauzy镶嵌--在磁场中的电子性质。它的能谱计算在紧束缚的方法通过递归方法。然后,我们研究了波包的量子动力学,讨论了磁场对扩散和谱指数的影响。最后,我们考虑了具有相同几何形状的准周期超导导线网络,并确定了临界温度作为磁场的函数。

英文摘要:

We study the electronic properties of a two-dimensional quasiperiodic tiling, the isometric generalized Rauzy tiling, embedded in a magnetic field. Its energy spectrum is computed in a tight-binding approach by means of the recursion method. Then, we study the quantum dynamics of wave packets and discuss the influence of the magnetic field on the diffusion and spectral exponents. Finally, we consider a quasiperiodic superconducting wire network with the same geometry and we determine the critical temperature as a function of the magnetic field.
