Spectral analysis of the 2+1 fermionic trimer with contact interactions
Simon Becker, Alessandro Michelangeli, Andrea Ottolini
We qualify the main features of the spectrum of the Hamiltonian of point interaction for a three-dimensional quantum system consisting of three point-like particles, two identical…

Conditional quasi-exact solvability of the quantum planar pendulum and of its anti-isospectral hyperbolic counterpart
Simon Becker, Marjan Mirahmadi, Burkhard Schmidt +2
We have subjected the planar pendulum eigenproblem to a symmetry analysis with the goal of explaining the relationship between its conditional quasi-exact solvability (C-QES) and t…
