They were differed by the contamination of fluorine and oxygen atoms; see for details [23]. Like to the classification of organic conductors proposed for doped trans-polyacetylene (t-PA) [24], the samples studied can be attributed both to highly doped carbynes and to carbynoids that is to materials including a wide range of carbyne-like structures.…”

Matrix-operator difference-differential equations for dynamics of spectroscopic transitions in 1D multiqubit exchange-coupled (para)magnetic and optical systems by strong dipole-photon and dipole-phonon coupling are derived within the framework of quantum field theory. It has been established that by strong dipole-photon and dipole-phonon coupling the formation of long-lived coherent system of the resonance phonons takes place, and relaxation processes acquire pure quantum character. It is determined by the appearance of coherent emission process of EM-field energy, for which the resonance phonon system is responsible. Emission process is accompanied by phonon Rabi quantum oscillation, which can be time-shared from photon quantum Rabi oscillations, accompanying coherent absorption process of EM-field energy. For the case of radio spectroscopy, it corresponds to the possibility of the simultaneous observation along with (para)magntic spin resonance, the acoustic spin resonance.

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...

“…Therefore, it was shown, that the carbon in 1D allotropic form possesses by very interesting quantum physical properties. Let us remark, that strict experimental proof of the existence of carbon in 1D allotropic form was obtained by electron spin resonance method, that is by one of the most powerful [and, consequently, the most reliable] experimental methods for the studies of quantum physics phenomena [25]. Physical explanation of the possipility of existence of carbon in 1D allotropic form is rather simple.…”

The symmetry studies of Maxwell equations gave new insight on the nature of electromagnetic (EM) field. Tey are reviewed in the work presented. It is drawing the attention on the following aspects.EM-field has in general case quaternion structure, consisting of four independent field constituents, which differ from each other by the parities under space inversion and time reversal.Any complex relativistic field has the gauge invariant conserving quantity -two-component scalar or pseudoscalar value -complex charge.There exists physical conserving quantity, which is simultaneously invariant under both Rainich dual and additional hyperbolic dual symmetry transformation of Maxwell equations. It is spin in general case or spirality in the corresponding geometry. EM-field is described instead of unobservable vector and scalar potentials by observable electric field 4-vector-function with the components Eα( r, t) = {Ex( r, t), Ey( r, t), Ez( r, t), i cρe( r,t) λ } and (or in the case of free EM-field) by means of magnetic field 4-vector-function Hµ( r, t) = {Hx( r, t), Hy( r, t), Hz( r, t), i cρm( r,t) λ }, where icρe( r, t), icρm( r, t) are the j4( r, t)-component of 4current density, corresponding to contribution of electric and magnetic component of charge densities correspondingly, λ is conductivity, which for the case of EM-field propagation in vacuum is λv = 1 120π (Ohm) −1 . Generalized Maxwell equations for quaternion four-component EM-field are obtained. Invariants for EM-field, consisting of dually symmetric parts are found. The main postulate of quantum mechanics: "To any mechanical quantity can be set up in the correspondence the Hermitian matrix by quantization" was proved.Canonical Dirac quantization method was developed in two aspects. The first aspect is its application the only to observable quantities. The second aspect is the realization along with well known time-local quantization of space-local quantization and space-time-local quantization. It is also shown, that Coulomb field can be quantized in 1D and 2D systems.New model of photons is proposed. The photons in quantized EM-field are main excitations in oscillator structure of EM-field, which is equivalent to spin S = 1 "boson-atomic" 1D lattice structure, consisting of the "atoms" with zeroth rest mass. The photons of the first kind and of the second kind represent themselves respectively neutral chargeless spin 1/2 EM-solitons and charged spinless EM-solitons of Su-Schrieffer-Heeger family.
