a b s t r a c tThe analytical solution of the task of the interaction of quantized EM-field with axially symmetric quasi-1D multichain qubit system by taking into account both the intrachain and interchain qubit coupling has been obtained for the first time. The appearance in stationary optical spectra of complementary lines, which is consequence of quantum nature of EM-field, leading to Rabi wave packets' formation, is predicted for all quasi-1D systems with strong electron-photon interaction. The model proposed is considered on the example of perfect carbon quasi-1D zigzag shaped nanotubes, for which a new quasi-1D model, which is qualitatively different from well-known 2D-model, is proposed.Ó 2011 Elsevier B.V. All rights reserved.Quantum electrodynamics (QED) consideration of interaction of electromagnetic (EM) field with matter is used at present very rare in practical applications, for instance, quantum nature of EM-field is not taken into account by its interaction with nanoobjects like to carbon nanotubes (NTs), both in theoretical and experimental aspects [1,2]. There exists at present in QED-theory the analytical solutions of the task of the interaction of quantized EM-field with one qubit, that is the Jaynes-Cummings model (JCM), with multiqubit systems without interaction between qubits, that is the Tavis-Cummings model, and the model described in [3], which is the generalization of Tavis-Cummings model by taking into account the 1D-coupling between qubits. The model to be considered continues the given series, that is, it is the model of the interaction of quantized EM-field with quasi-1D multichain qubit system by taking into account both the intrachain and interchain qubit couplings without restriction on their values. Quasi-1D carbon zigzag-shaped nanotubes (CZSNTs) will represent multichain qubit system in the formulated task above.Quasi-1D CZSNTs can be considered (see further) to be the set of carbon backbones of trans-polyacetylene (t-PA) chains, which are connected between themselves, that is the qualitatively different model for quasi-1D CZSNTs will be proposed in comparison with the well-known 2D-model of NTs. The necessity in the given model is determined by analysis of experimental results, indicating, that with decrease of tube diameter the 2D-1D transition takes place and all physical properties of carbon NTs undergo qualitative leap. It is relevant to both the kinds of NTs, that is to rather perfect NTs produced by high energy ðP 1 Mev per nucleonÞ ion modification (HEIM) of diamond single crystals [4-6] and the so-called ultra-small NTs with 0.4 nm diameter, produced [7,8] inside the nanochannels of porous zeolite AlPO4-5 single crystals. It is interesting, that the authors of [7,8] are considering 0.4 nm diameter single wall nanotubes (SWNTs) to be ideal one-dimensional quantum hollow wires, that is in fact they come to the same conclusion concerning the 2D-1D transition presence. Analogous conclusion was recently done in [9] by electron spin resonance studies (ESR) of ultra-small NT...

QED-model for multichain coupled qubit system, proposed in [1], was confirmed by Raman scattering studies of carbon zigzag-shaped nanotubes, produced by high energy ion beam modification of natural diamond single crystals. New quantum optics phenomenon -Rabi waves -has been experimentally identified for the first time. Raman spectra in perfect quasi-1D carbon nanotubes are quite different in comparison with well known Raman spectra in 2D carbon nanotubes of larger diameter. They characterized by vibronic mode of Su-Schriffer-Heeger σ-polaron lattice and its revival part in frequency representation, which is the consequence of Rabi wave packet formation.
