Query: Compacton matter waves in binary Bose gases under strong nonlinear
  management   The existence of compacton matter waves in binary mixtures of quasi
one-dimensional Bose-Einstein condensates in deep optical lattices and in the
presence of nonlinearity management, is first demonstrated. For this, we derive
an averaged vector discrete nonlinear Schr\"odinger equation (DNLSE) and show
that compacton solutions of different types can exist as stable excitations.
Stability properties are studied by linear analysis and by direct numerical
integrations of the DNLSE system and their dependence on the inter- and
intra-species scattering lengths, investigated. We show that under proper
management conditions, compactons can be very robust excitations that can
emerge spontaneously from generic initial conditions. A possible experimental
setting for compacton observation is also discussed.
