摘要：

We introduce an exactly solvable model for trapped three-color atom gases. Application to a system of cigar-shaped trapped cold fermions reveals a complex structure of breached pairing phases. We find two competing superfluid phases at weak and intermediate couplings, each with two-color pair condensates that can be distinguished with density profile measurements.
