WebThe Gross–Pitaevskii equation (GPE, named after Eugene P. Gross and Lev Petrovich Pitaevskii) describes the ground state of a quantum system of identical bosons using the Hartree–Fock approximation and the pseudopotential interaction model.. A Bose–Einstein condensate (BEC) is a gas of bosons that are in the same quantum state, and thus can … Webnamely, Nonlinear Schrodinger (NLS) equation and Gross-Pitaevskii equation (GPE).¨ Method Active Learning is selecting data in an iterative fashion to improve model performance by maximizing infor-mation acquisition with limited training samples. AL adds a certain cleverness on which samples to choose to improve the model’s accuracy.
