Degeneracy of Landau levels and quantum group slq(2).
نویسندگان
چکیده
We show that there is a kind of quantum group symmetry slq(2) in the usual Landau problem and it is this quantum group symmetry that governs the degeneracy of Landau levels. We find that under the periodic boundary condition, the degree of degeneracy of Landau levels is finite, and it just equals the dimension of the irreducible cyclic representation of the quantum group slq(2).

Applications of Quantum Group to Fractional Quantum Hall Effect
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 i...
متن کاملW∞ and SLq(2) Algebras in the Landau Problem and Chern-Simons Theory on a Torus
We discuss w∞ and slq(2) symmetries in Chern-Simons theory and Landau problem on a torus. It is shown that when the coefficient of the ChernSimons term, or when the total flux passing through the torus is a rational number, there exist in general two w∞ and two slq(2) algebras, instead of one set each discussed in the literature. The general wavefunctions for the Landau problem with rational to...

Considering a multi-dimensional q-oscillator invariant under the (non quantum) group U(n), we construct a q-deformed Levi-Civita epsilon tensor from the inner product states. The invariance of this q-epsilon tensor is shown to yield the quantum group SLq(n) and establishes the relationship of the U(n) invariant q-oscillator to quantum groups and quantum group related oscillators. Furthermore th...
متن کاملQuantum mechanics and quantum Hall effect on Riemann surfaces
The quantum mechanics of a system of charged particles interacting with a magnetic field on Riemann surfaces is studied. We explicitly construct the wave functions of ground states in the case of a metric proportional to the Chern form of the θ-bundle, and the wave functions of the Landau levels in the case of the the Poincaré metric. The degeneracy of the the Landau levels is obtained by using...
متن کاملNon-Abelian Geometrical E ect in Quantum Adiabatic Transitions
We establish a new formula for the probability of a quantum adiabatic transition between two permanently degenerated energy-levels which do not cross. This formula corresponds to the non-abelian generalization of the Landau-Dykhne formula valid for the non-degenerate case. It applies in particular in cases of symmetry induced degener-acy, a typical example being the Kramer's degeneracy.
