We briefly summarize the most relevant steps in the search of rigorous results about the properties of quantum systems made of three bosons interacting with zero-range forces. We also describe recent attempts to solve the unbounded- ness problem of point-interaction Hamiltonians for a three-boson system, keeping unaltered the spectrum structure at low energies.

Abstract
We briefly summarize the most relevant steps in the search of rigorous results about the properties of quantum systems made of three bosons interacting with zero-range forces. We also describe recent attempts to solve the unbounded- ness problem of point-interaction Hamiltonians for a three-boson system, keeping unaltered the spectrum structure at low energies.File allegati a questo prodotto
