高朗道能级的离散相干态

Discrete coherent states for higher Landau levels

L. D. Abreu, P. Balazs, M. de Gosson, Z. Mouayn

摘要:

我们考虑带电粒子在恒定均匀磁场作用下演化的量子动力学,重点是海森堡群(在欧几里德情形下)和SL(2,R)群(在双曲情形下)的离散子群。我们研究了高阶欧氏和双曲朗道能级的离散相干态的完备性,部分推广了Perelomov和Bargmann,Butera,Girardello和Klauder的经典结果.在欧几里德的情况下,我们的结果如下从识别的完备性问题与已知的结果从理论的Gabor框架。双曲线设置的结果,然后使用相干态,时间尺度分析和Fuchsian群及其相关自守形式的理论的方法相结合。

英文摘要:

We consider the quantum dynamics of a charged particle evolving under the action of a constant homogeneous magnetic field, with emphasis on the discrete subgroups of the Heisenberg group (in the Euclidean case) and of the SL(2, R) group (in the Hyperbolic case). We investigate completeness properties of discrete coherent states associated with higher order Euclidean and hyperbolic Landau levels, partially extending classic results of Perelomov and of Bargmann, Butera, Girardello and Klauder. In the Euclidean case, our results follow from identifying the completeness problem with known results from the theory of Gabor frames. The results for the hyperbolic setting follow by using a combination of methods from coherent states, time-scale analysis and the theory of Fuchsian groups and their associated automorphic forms.
