      The exact solutions for the two-dimensional motion of a conduction band electron in a disc shaped quantum dot are used to calculate the optical absorption as well as the corrections to the refractive index in the system. The cover shows the probability density corresponding to the first excited electron state as in figure 3 of the article. Picture: C. M. Duque, M. Mora-Ramos, C. A. Duque, pp. 327–337, in this issue.

      On the quantum statistics of bound states within the Rutherford model of matter (pages 311–326)

      W. Ebeling, W.-D. Kraeft and G. Röpke

      Article first published online: 16 APR 2012 | DOI: 10.1002/andp.201100331

      Thumbnail image of graphical abstract

      The quantum statistical treatment of the Rutherford model, considering matter as a system of point charges (electrons and nuclei), is analyzed. The modern state of art is presented and new results are given which explain why bound states according to a discrete part of the spectra occur only in a valley in the temperature-density plane.

    1. Quantum disc plus inverse square potential. An analytical model for two-dimensional quantum rings: Study of nonlinear optical properties (pages 327–337)

      C.M. Duque, M.E. Mora-Ramos and C.A. Duque

      Article first published online: 22 MAY 2012 | DOI: 10.1002/andp.201200055

      Thumbnail image of graphical abstract

      The exact solutions for the two-dimensional motion of a conduction band electron in a disc shaped quantum dot are used to calculate the linear and nonlinear optical absorption as well as the linear and nonlinear corrections to the refractive index in the system. It is shown that this kind of structure may work well as a model for a quantum ring.

    2. On the interaction between an electric quadrupole moment and electric fields (pages 338–344)

      K. Bakke

      Article first published online: 17 APR 2012 | DOI: 10.1002/andp.201100322

      Thumbnail image of graphical abstract

      In this work, quantum effects are discussed which arise from the interaction between an electric quadrupole moment and electric fields. It is shown that, by choosing a diagonal electric quadrupole tensor whose components are constants, the interaction between an electric quadrupole moment and electric fields gives rise to the scalar Aharonov-Bohm effect and to bound states analogous to the confinement of a quantum particle to a quantum dot.

    3. Alternative approach to the solution of the momentum-space Schrödinger equation for bound states of the N-dimensional Coulomb problem (pages 345–352)

      R. Szmytkowski

      Article first published online: 19 MAR 2012 | DOI: 10.1002/andp.201100330

      Thumbnail image of graphical abstract

      The Schrödinger–Coulomb problem in ℝN, N ≥ 2, is considered in the momentum representation. The adjoint Sturmian eigenvalue problem is discussed. The resulting radial integral equation is solved with the aid of a symmetric Poisson-type series expansion of the Legendre function of the second kind into products of the Gegenbauer polynomials, established by Ossicini.

    4. Supersymmetric solution of Schrödinger equation by using the asymptotic iteration method (pages 353–359)

      G. Kocak, O. Bayrak and I. Boztosun

      Article first published online: 15 MAY 2012 | DOI: 10.1002/andp.201200028

      In this work, the exact analytical solutions of the radial Schrödinger equation are presented for the harmonic oscillator, Hulthén and Pöschl-Teller potentials within the framework of the asymptotic iteration method by using supersymmetry. The energy eigenvalues and the corresponding eigenfunctions are obtained analytically.

    5. Real exact solutions to the relativistic spinless particle with modified Rosen–Morse potential and its ���� symmetry (pages 360–365)

      W.-C. Qiang, G.-H. Sun and S.-H. Dong

      Article first published online: 24 APR 2012 | DOI: 10.1002/andp.201200030

      Thumbnail image of graphical abstract

      The real exact solutions to the relativistic spinless particle with modified Rosen--Morse potential are presented. As a novel aspect, the previously obtained eigenfunctions related to this type of potential in an imaginary variable i sinh (α x) (Dirac case) can be expressed by the real Nomanovski polynomials. The energy levels are calculated numerically.

    6. Teleparallel gauge theory of gravity (pages 366–370)

      J.W. Maluf and F.F. Faria

      Article first published online: 15 MAY 2012 | DOI: 10.1002/andp.201200037

      n this work a tetrad theory of gravity, invariant under conformal transformations, is investigated. The action of the theory is similar to the action of Maxwell's electromagnetism. The role of the electromagnetic gauge potential is played by the trace of the torsion tensor of the Weitzenböck spacetime. It is shown that all static, spherically symmetric space-times are solutions of the vacuum field equations.

    7. Model-independent constraints on r-3 extra-interactions from orbital motions (pages 371–377)

      L. Iorio

      Article first published online: 15 MAY 2012 | DOI: 10.1002/andp.201200060

      Thumbnail image of graphical abstract

      Constraints on long-range power-law modifications Upert ∝ r-3 of the usual Newtonian gravitational potential UN ∝ r-1 are inferred from orbital motions of well known artificial and natural bodies. They can be interpreted in terms of a characteristic length ℓ which may be identified with, e. g., the antide Sitter (AdS) radius of curvature ℓ in the Randall-Sundrum (RS) braneworld model.
