Magneto-Skyrmion excitations of bilayer electron-hole fluids

The exciton condensate of bilayer electron-hole fluids has been a topic of both experimental and theoretical interest in recent years. In this talk we will discuss the influence of strong perpendicular magnetic fields on bilayer electron-hole fluids. In the limit of very strong fields exciton condensation occurs for both electron-hole and electron-electron fluids. We show that although condensate states are more persistent in the electron-hole case, they are interrupted by incompressible quantum Hall states when the magnetic field is strong and the densities of both electrons and holes are close to integer Landau level filling factors. Non-zero angular momentum condensates can be stabilized when the filling factors of electrons and holes differ. At strong fields the ground states of charged electron-fluids can be unstable to the formation of states with lattices of magneto-Skyrmions, charged textures with strong hole polarization in the core of condensate vortices. We will discuss strategies to observe magneto-Skyrmion lattices experimentally.
