- (3 pts.) Create a Python function which will return the two-particle two-hole pairing model Hamiltonian for a given value of g and d. Do the same for the four-particle four-hole pairing model Hamiltonian.
- (3 pts.) Create a function which will take as an input a Hamiltonian matrix and return the ground state energy.
- (2 pts.) Based on your current understanding (or using the other resources with citations) explain the no-broken pairs pairing model.
- (2 pts.) Based on your current understanding (or using the other resources with citations) explain why we cannot always use eigenvalue solvers to find the ground state energy.
