Discovery of the Relativistic Schrödinger Equation
Kamal Barley, José Vega-Guzmán, Andreas Ruffing +1
We discuss the discovery of the relativistic wave equation for a spin-zero charged particle in the Coulomb field by Erwin Schrödinger (and elaborate on why he didn't publish it).
Some cubic birth and death processes and their related orthogonal polynomials
Jacek Gilewicz, Elie Leopold, Andreas Ruffing +1
The orthogonal polynomials with recurrence relation \[(\la\_n+μ\_n-z) F\_n(z)=μ\_{n+1} F\_{n+1}(z)+\la\_{n-1} F\_{n-1}(z)\] with two kinds of cubic transition rates $\la\_n$ and $μ…
The First Moment of delta g(x) -- a Comparative Study
Bodo Lampe, Andreas Ruffing
The sensititivity of various future polarization experiments to the first moment Delta g of the polarized gluon density is elucidated in detail. It is shown to what extent the firs…
A q-Deformation of the Harmonic Oscillator
A. Lorek, A. Ruffing, J. Wess
The q-deformed harmonic oscillator is studied in the light of q-deformed phase space variables. This allows a formulation of the corresponding Hamiltonian in terms of the ordinary…
String branchings and complex tori and algebraic representations of generalized Krichever-Novikov algebras
Andreas Ruffing, Thomas Deck, Martin Schlichenmaier
The propagation differential for bosonic strings on a complex torus with three symmetric punctures is investigated. We study deformation aspects between two point and three point d…
