They proposed that anisotropic potentials in artificial atoms could induce hybridization between confined states of different orbitals, such as the s orbital (orbital quantum number 0) and the d ...

with a quantum number of 2. Upper panels: The schematic plots of (a) unhybridized orbitals and (b) sp2 orbital hybridization in real atoms. Lower panels: The schematic plots of (c) circular potential ...
