Over the last two decades, multiphoton microscopy has created a renaissance in the brain imaging community. It has changed how we visualize neurons by providing high-resolution, non-invasive imaging capability deep within intact brain tissue. Multiphoton imaging will likely play an essential role in understanding how the brain works at the level of neural circuits, which will provide a bridge between microscopic interactions at the neuronal level and the complex computations performed at larger scales.

Motivated by work in nonlinear optics, as well as more recently
in Bose-Einstein condensate mixtures, we will explore a
series of nonlinear states that arise in such systems. We
will start from a single structure, the so-called dark-bright solitary wave, and then
expand our considerations to multiple such waves, their
spectral properties, nonlinear interactions and experimental
observations. A twist will be to consider the dark
solitons of the one component as effective potentials that will trap the bright
