dc.description.abstract	We study theoretically the quantum states of two interacting excitons in coaxial double quantum rings. An interplay between exciton-exciton Coulomb interactions and specific geometry of the structure leads to the emergence of peculiar energy spectrum of two exciton system. We develop a semi-analytic approach providing highly accurate energies of system in the wide range of values of geometrical parameters relevant to experimental realizations.
