We study the formation of stripe order within the SO(5) theory of high Tc superconductivity. We show that spin and charge modulations arise as a result of the competition between a local tendency to phase separate and the long-range Coulomb interaction. This frustrated phase separation leads to hole-rich and hole-poor regions which are respectively superconducting and antiferromagnetic. A rich variety of microstructures ranging from droplet and striped to inverted-droplet phases are stabilized, depending on the charge carrier concentration. We show that the SO(5) energy functional favors non-topological stripes.
