Effective Hamiltonian and excitation spectrum of harmonically trapped bosons

Effective Hamiltonian and excitation spectrum of harmonically trapped bosons

An approach is proposed to obtain an effective Hamiltonian of a harmonically trapped Bose-system. Such a Hamiltonian is quadratic in the creation–annihilation operators and certain approximations allow to simplify higher (three and four operator) products to the required form. After the Hamiltonia...
