Abstract:
In many body physics, we are usually faced with the intractable problem of finding the ground state wavefunction of a thermo dynamic ally large system of interacting particles. Typically this problem is solved perturbatively. That is, we start with some simple noninteracting Hamiltonian and its ground state (e.g. the free Fermi gas) and perturb in the interactions (e.g. the Coulomb potential):
HamiltonianH → perturbationtheory → groundstate|Ψ.
