AB  - We analyzed linear molecular chain with exciton excitations for the case when number of excitons is not conserved. The results obtained are in some sense amazing. The dispersion law of finite chain is surface depending on two independent angles. The same conclusion is valid for concentrations of exitons and exciton pairs. As it was expectable physical characteristics of the finite chain depend on spatial coordinates. All results are compared to corresponding results of infinite chain.

AB  - In connection with the experimental result which stated that polyethylene foil amplifies about three times the penetrated light, we propose two theoretical explanations of this phenomenon. One of them is that several amplified peaks are the consequence of the forming of solitons in a polyethylene chain whose velocities are close to the velocity of sound. Forming of solitons, together with boundary conditions in a polyethylene macromolecules chain, which contain about thirty monomers, lead to the amplification of light. The second explanation requires introduction of homeopolar excitons in polymer macromolecules. Both energy gap of homeopolar excitons and width of homeopolar exciton zone are of the same order of magnitude. It means that transitions in a very wide zone give light quanta which are able to amplify the initial light. In order to avoid some confusion and misunderstandings, we wish to point out the following. Atoms and molecules as the whole are treated classically (transition through potential barriers, for example, etc.). The exception to this rule are phonon theories of crystals where the phonon is considered as a quanta of boson field, i.e., it means that, in the theory of mechanical oscillations, molecules and atoms as the whole are treated quantum mechanically. On the other hand, elementary excitations in crystals such as excitons, vibrons, spin waves, and ferroelectric excitations, etc., which arise from changes of some parts of atoms or molecules are treated quantum mechanically exclusively. In the analyses of this work, the excitations of an individual molecule subsystem (i.e. the quantum objects) would serve as an explanation of the light amplification by a polymer chain.

AB  - In the nanocylinder, a cut-off from the molecular crystal, dielectric permeability tensor is investigated. Excitons in the nanocylinder arise due to the exciting of the electron subsystem of the molecule. In evaluation of dielectric permeability Dzhyaloshinskii-Pitaevskii approach is used, connected with retarded and advanced exciton Green's functions and correct use of Paulion Green's function. It turned out that refraction and absorption indices depend on configuration coordinates, having maximal values at boundary cross-sections and minimal value at central cross-section of the nanocylinder broken symmetry structure. Although it was expected that boundary conditions make higher refractive and absorptive characteristics of the nanocylinder, this appeared not to be possible because Paulion Green's function is not proportional to the exciton concentration.

AB  - Two unresolved issues of the (semi)classically addressed problems in molecular biophysics are unreasonably long time necessary for the change of biopolymer conformations and long-range directedness of selective biomolecular recognition processes - implying their essential quantum origin. In this paper several possible quantum approaches to biomolecular recognition are considered: Theory of Non-Radiative Resonant Structural Transitions, Model of Quantum Decoherence, and Resonant Recognition Model. These approaches might be of fundamental importance in understanding underlying macroscopic quantum-holographic Hopfield-like control mechanisms of morphogenesis, and their backward influence on the expression of genes, with significant potential psychosomatic implications.
AB  - Dva nerazrešena pitanja semi-klasično postavljnih problema u molekularnoj biofizici jesu nerazumno dugo vreme potrebno za izmenu biomolekularnih konformacija i dugo-dometna usmerenost selektivnih procesa biomolekularnog prepoznavanja. U radu je razmotreno nekoliko mogućih kvantnih prilaza rešavanju ovih problema. Predloženi kvalitativni scenario je dovoljno opšti i čini dobru osnovu za principijelno rešenje problema biopolimernog sklupčavanja u nativnu konformaciju pri visoko selektivnim procesima protein/receptor biomolekularnog prepoznavanja, implicirajući makroskopsku kvantnu nelokalnost na biološkom ćelijskom nivou. (Bazična nelokalnost se može proširiti i na makroskopski kvantni nivo biološkog organizma na šta ukazuje makroskopska kvantna mikrotalasna rezonantna terapija akupunkturnog sistema.) Kvantna priroda ovih procesa ilustrovana je na primeru neradijativnih strukturnih prelaza, modelu kvantne dekoherencije i modelu rezonantnog prepoznavanja uz diskusiju implementirajućeg mehanizma elektronsko-konformacione sprege u ključ-brava uklapajućim konformacionim prelazima biomolekularnog prepoznavanja protein/supstrat. Na osnovu ovih prilaza u stanju smo da reprodukujemo kako egzistenciju i stabilnost (stacionarnih) polimernih konformacija tako i kratka vremena za kvantno -mehaničke procese u konformacionim prelazima u selektivnim procesima biomolekularnog prepoznavanja. Pošto ovi procesi dovode do dinamičke modifikacije više-elektronske hiperpovrši energija-stanje ćelijskog protein/receptor ansambalskog biomolekularnog makroskopskog kvantnog sistema, to otvara mogućnost razmatranja ćelijskog biomolekularnog prepoznavanja kao Hopfildove kvantno-holografske asocijativne neuronske mreže.

AB  - The superconductivity properties of cylinder with nano cross-section are investigated. In the nearest neighbours approximation, electron Hamiltonian of cylinder decays onto two independent Hamiltonians. One corresponds to electrons which propagate along chains parallel to the axis of cylinder. Second correspond to electrons moving in discs. The electron-phonon interaction Hamiltonians are found and superconductive properties were examined in the frames of BCS approach. It was shown that superconductive temperature in chains is several Kelvins, while in discs it can be higher for two orders of magnitude. It is also shown that magnetic field produced by electron currents in discs is of the order of thousand Tesla, i.e., extremely high.
