Hamiltonians for Quantum Systems with Contact Interactions
Daniele Ferretti, Alessandro Teta
We discuss the problem of constructing self-adjoint and lower bounded Hamiltonians for a system of non-relativistic quantum particles in dimension three with contact (or zero…

Hamiltonian for a Bose gas with Contact Interactions
Daniele Ferretti, Alessandro Teta
We study the Hamiltonian for a three-dimensional Bose gas of spinless particles interacting via zero-range (also known as contact) interactions. Such interactions are en…
