Abstract:
This article concerns the standing waves of a linearly coupled Schrodinger
system which arises from nonlinear optics and condensed matter physics.
The coefficients of the system are spatially dependent and have a mixed
behavior: they are periodic in some directions and tend to positive
constants in other directions. Under suitable assumptions, we prove that
the system has a positive ground state. In addition, when the L-infinity-norm
of the coupling coefficient tends to zero, the asymptotic behavior of the
ground states is also obtained.
