A product named for this man assumes that the wavefunction of a quantum system is the product of its individual wavefunctions. For 10 points each:
[10m] Name this English physicist. He is the first namesake of an approximation which writes the wavefunction of a fermion as a single Slater determinant.
ANSWER: Douglas Hartree [or Hartree-Fock approximation; or Hartree product]
[10e] The nonlinear term of the Hartree equation comes from convolving with a negative power of the magnitude of this quantity. Heisenberg's uncertainty principle prevents knowing this quantity and momentum with arbitrary precision.
ANSWER: position
[10h] Convolving with a delta function in the Hartree equation yields the single-particle form of this nonlinear Schrödinger equation. This equation describes the ground state of identical bosons under the Hartree-Fock approximation, so can be used to model Bose-Einstein condensates.
ANSWER: Gross-Pitaevskii equation
