  We introduce a new integrable model to investigate the dynamics of two
component quasi particle condensates with spatio temporal interaction
strengths. We derive the associated Lax-pair of the coupled GP equation and
construct matter wave solitons. We show that the spatio temporal binary
interaction strengths not only facilitate the stabilization of the condensates,
but also enables one to fabricate condensates with desirable densities,
geometries and properties leading to the so called "designer quasi particle
condensates".
