Applications of Quantum Group to Fractional Quantum Hall Effect

چکیده

We show that there exists quantum group symmetry slq(2) in the fractional quantum Hall effect (FQHE) and this symmetry governs the degeneracy of groundstate level. Under the periodic boundary condition, the degree of degeneracy is related to the cyclic representation of slq(2). We also discuss the influence of impurity by using quantum group technique and give the energy correction due to the impurity potential. PACS number(s): 73.20H, 02.20.+b

Modular Invariance on the Torus and Fractional Quantum Hall Effect

The implementation of modular invariance on the torus at the quantum level is discussed in a group-theoretical framework. Two cases must be considered, depending on the cohomology class of the symplectic form on the torus. If it is of integer cohomology class n, then full modular invariance is achieved at the quantum level only for those wave functions on the torus which are periodic if n is ev...

Applications of Wavelets to Quantum Mechanics: a Pedagogical Example

We discuss in many details two quantum mechanical models of planar electrons which are very much related to the Fractional Quantum Hall Effect. In particular, we discuss the localization properties of the trial ground states of the models starting from considerations on the numerical results on the energy. We conclude that wavelet theory can be conveniently used in the description of the system...

بررسی اثر صحیح کوانتومی هال در سیستمهای دارای ناخالصی به روش تبدیل پیمانه‌ای در حضور نقطه‌های کوانتومی

In this paper we study the integer quantum Hall effect (IQHE) on the systems with different types of impurities in delta and gaussian forms. The Landau energy levels in the presence of impurity split in two different levels,the extended and localized levels, emerging then the Hall step. Finally, we add a specified form of a quantum dot potential to a system with impurity, and observed that incr...

Noncommuting coordinates in the Hall effect and in vortex dynamics

Laughlin’s Ansatz to explain the fractional Quantum Hall effect is derived by coupling a particle associated with “exotic” the two-fold central extension of the planar Galilei group. The reduced system is identical to the one used to describe the dynamics of vortices in an incompressible planar fluid.

Mutual statistics, braid group, and the fractional quantum Hall effect

We show that the notion of mutual statistics arises naturally from the representation theory of the braid group over the multi-sheeted surface. A Hamiltonian which describes particles moving on the double-sheeted surface is proposed as a model for the bilayered fractional quantum Hall effect (FQHE) discovered recently. We explicitly show that the quasi-holes of the bilayered Hall fluid display ...
