abstract = "An effective method for computing excitonic shifts in curved quantum-wire geometries is presented. As a case example, we consider a GaAs quantum ring with infinite barriers along the cross-sectional dimensions assumed to be of square shape albeit this assumption can be easily avoided. A simple analytic expression for excitonic shifts is found using first-order perturbation theory.",
