The Thomas-Fermi approximation ignores the kinetic energy operator in the (*) Gross-Pitaevskii equation, which describes its zero-temperature properties.
Its creation and annihilation operators can be replaced by their expectation values according to the Bogoliubov approximation. The Thomas-Fermi approximation ignores the kinetic energy operator in the (*) Gross-Pitaevskii equation, which describes its zero-temperature properties. It involves the formation of a shared low energy quantum state of integer spin particles and was first observed in gaseous rubidium atoms. For 10 points, name this substance in which particles coalesce into a single quantum mechanical entity.
Its creation and annihilation operators can be replaced by their expectation values according to the Bogoliubov approximation.
