On the discrete spectrum of spin-orbit Hamiltonians with singular interactions
Jochen Bruening, Vladimir Geyler, Konstantin Pankrashkin
We give a variational proof of the existence of infinitely many bound states below the continuous spectrum for spin-orbit Hamiltonians (including the Rashba and Dresselhaus cases)…
A Three Parameter Hopf Deformation of the Algebra of Feynman-like Diagrams
Gérard Henry Edmond Duchamp, Pawel Blasiak, Andrzej Horzela +2
We construct a three-parameter deformation of the Hopf algebra $\LDIAG$. This is the algebra that appears in an expansion in terms of Feynman-like diagrams of the {\em product form…
The integrated density of states for an interacting multielectron homogeneous model
Frederic Klopp, Heribert Zenk
For a system of n interacting electrons moving in the background of a "homogeneous" potential, we show that, if the single electron Hamiltonian admits a density of states, so does…
Geometric tools of the adiabatic complex WKB method
Alexander Fedotov, Frederic Klopp
The paper is devoted to the description of the main geometric and analytic tools of a complex WKB method for adiabatic problem. We illustrate their use by numerous examples.
