It is known that when the Hamiltonian of a system is invariant under a symmetry operation, but the ground state is not, the symmetry of the system can be spontaneously broken [17].

In particular, these experiments revealed that the res onant frequencies are independent of the number of electrons in a QD [5] and can be associated with the eigenmodes of the Hamiltonian of the model describ ing the electron dynamics in an external magnetic field in the potential of a two dimensional isotropic harmonic oscillator [6].

To prove the N P-hardness of the problem, we will use a reduction from the Hamiltonian path problem, which is known to be N P-complete [?].

Namely, if G is a compact and connected Lie group, they classify the Hamiltonian Lie group actions up to equivariant symplectomorphisms, by providing an injective functor between the category of Hamiltonian Lie group actions and the category of symplectic representation of closed subgroup of G, an Hamiltonian Lie group action being canonically symplectomorphic to the cotangent bundle symplectic quotient, this provides an answer to the question in this precise case.

There is a general agreement that for heavy-fermion compounds, the model Hamiltonian is well established (the periodic Anderson model or the periodic Kondo lattice), and the main theoretical challenge in this case lies in constructing accurate approximations.
