Exciton–Exciton Interactions in Coaxial Double Quantum Rings
Publisher's version (útgefin grein) 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 e...
