A multi particle toy system with analytic solutions to investigate composite bosons in a harmonic potential
Abstract
We construct a three dimensional toy systems with two types of fermions forming a composite boson. They are hold in a harmonic potential. The basis functions are constructed from an internal and an external Gauss function. All integrals have analytical solutions. The high symmetry reduces the number of integrals to be calculated for the symmetrized wave functions. With the internal Gauss function the composite bosons can be tuned from fermionic unbound behavior to bosonic bound behavior.
