چکیده
We discuss supersymmetric biorthogonal systems, with emphasis given to the periodic solutions that occur at spectral singularities of PT symmetric models. For these periodic solutions, the dual functions are associated polynomials that obey inhomogeneous equations. We construct in detail some explicit examples for the supersymmetric pairs of potentials V± (z) = −U (z) 2 ±z d dz U (z) where U (z) ≡ ∑ k>0 υkz . In particular, we consider the cases generated by U (z) = z and z/ (1− z). We also briefly consider the effects of magnetic vector potentials on the partition functions of these systems. *[email protected], [email protected], & [email protected]

Biorthogonal Quantum Systems
Models of PT symmetric quantum mechanics provide examples of biorthogonal quantum systems. The latter incorporporate all the structure of PT symmetric models, and allow for generalizations, especially in situations where the PT construction of the dual space fails. The formalism is illustrated by a few exact results for models of the form H = (p+ ν)2 + ∑ k>0 μk exp (ikx). In some non-trivial ca...
متن کاملSuper algebra and Harmonic Oscillator in Anti de Sitter space
The harmonic oscillator in anti de Sitter space(AdS) is discussed. We consider the harmonic oscillator potential and then time independent Schrodinger equation in AdS space. Then we apply the supersymmetric Quantum Mechanics approach to solve our differential equation. In this paper we have solved Schrodinger equation for harmonic oscillator in AdS spacetime by supersymmetry approach. The shape...

متن کاملSupersymmetric Quantum Mechanics from Light Cone Quantization
We study the supersymmetric quantum mechanical systems that arise from discrete light cone quantization of theories with minimal supersymmetry in various dimensions. These systems which have previously arisen in the study of black hole moduli spaces, are distinguished by having fewer fermionic fields than the familiar Kähler and hyper-Kähler models. This is a contribution to the Yuri Golfand me...
متن کاملNew biorthogonal potential–density basis functions
We use the weighted integral form of spherical Bessel functions, and introduce a new analytical set of complete and biorthogonal potential–density basis functions. The potential and density functions of the new set have finite central values and they fall off, respectively, similar to r and r at large radii where l is the latitudinal quantum number of spherical harmonics. The lowest order term ...
