Paper Abstract
Quantum mechanics explains the existence and properties of the chemical bond responsible for the formation of
molecules from isolated atoms. In this work we study quantum states of Double Quantum Wells, DQW, formed from
isolated Single Quantum Wells, SQWs, that can be considered metamaterials. Using the quantum chemistry definition of
the covalent bond, we discuss molecular states in DQW as a kind of nanochemistry of metamaterials with new
properties, in particular new optical properties. An important particularity of such nanochemistry, is the possible
experimental control of the geometrical parameters and effective masses characterizing the semiconductor
heterostructures represented by the corresponding DQW. This implies a great potential for new applications of the
controlled optical properties of the metamaterials. The use of ab initio methods of intensive numerical calculations
permits to obtain macroscopic optical properties of the metamaterials from the fundamental components: the spatial
distribution of the atoms and molecules constituting the semiconductor layers. The metamaterial new optical properties
emerge from the coexistence of many body processes at atomic and molecular level and complex quantum phenomena
such as covalent-like bonds at nanometric dimensions.
