Isomeric electronic states in concentric quantum rings
(2009) In Physical Review B (Condensed Matter and Materials Physics) 79(24).- Abstract
- We show that polarized few-electron concentric double quantum rings display localized states that are the quantum analog of classical equilibrium ones. These states have very similar energies but fairly different angular momenta, constituting a new physical realization of the isomeric states found in nuclear and molecular physics. Their fingerprint is a very soft mode in the infrared-absorption spectrum at nearly the dipole excitation energy of a rigidly rotating N-electron molecule. The yrast line and the infrared-absorption spectrum are discussed for N=4 and 6 electron configurations.
