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…
Multiplicity of self-adjoint realisations of the (2+1)-fermionic model of Ter-Martirosyan-- Skornyakov type
Alessandro Michelangeli, Andrea Ottolini
We reconstruct the whole family of self-adjoint Hamiltonians of Ter-Martirosyan-- Skornyakov type for a system of two identical fermions coupled with a third particle of different…
On point interactions realised as Ter-Martirosyan-Skornyakov Hamiltonians
Alessandro Michelangeli, Andrea Ottolini
For quantum systems of zero-range interaction we discuss the mathematical scheme within which modelling the two-body interaction by means of the physically relevant ultra-violet as…
