The role of solitons in charge and energy transfer in 1D molecular chains
(Physica. D: Nonlinear Phenomena, 1998)
The idea that polarons and solitons could play the crucial role in the transport processes in biological structures, has been critically reexamined on the basis of the general theory of self-trapping phenomena. The criteria ...
The relation between the scaling of Husimi functions and the linear phase insensitive amplification of the corresponding quantum states and its implications
(Journal of Physics. A: Mathematical and General, 1996)
Using the description of the linear phase insensitive amplification of a quantum state available in the literature we prove that to every state rho(t), produced from the initial state rho(0) by such amplification, there ...
Effects of quantum lattice fluctuations on multiquanta Davydov-like solitons in a molecular chain
(Journal of Physics: Condensed Matter, 1997)
The dressing effect due to the quantum nature of phonons may cause the creation of bound states of several vibrons in the molecular chain. The possibility of creating soliton states of this type is discussed for the simple ...
Preparation and molecular structure of the trans(O-6) isomer of dihydrogen (1,3-propanediamine-N,N-diacetato-N,N-di-3-propionato)copper(II) complex. The stereochemistry of copper(II)-EDTA-type complexes in relation to the structure of the ligand
(Polyhedron, 1996)
The hexadentate complex [Cu(H(2)1,3-pddadp)]. 1.5H(2)O (1,3-pddadp = 1,3-propanediamine-N,N-diacetate-N,N-di-3-propionate ion) has been prepared and isolated and its molecular structure determined by the single crystal ...
Similarity of structure properties of Hg1-xMnxS and Cd1-xMnxS (structure properties of HgMnS and CdMnS)
(Journal of Magnetism and Magnetic Materials, 1996)
We report the structural parameters and their variation with manganese concentration for the diluted magnetic semiconductors Hg1-xMnxS (x less than or equal to 0.33) and Cd1-xMnxS (x less than or equal to 0.43), as obtained ...
Finite-temperature two-state small-polaron dynamics: Averaged Hamiltonian approach
(Journal of Physics: Condensed Matter, 1996)
We study small-polaron self-trapping properties in the two-state molecular crystal model by employing a finite-temperature variational non-adiabatic approach that is an extension to the semiclassical adiabatic Pekar theory. ...
Kinetic properties of multiquanta Davydov-like solitons in molecular chains
(Physical Review E, 1999)
The Fokker-Planck equation for multivibron solitons interacting with lattice vibrations in a molecular chain has been derived by means of the nonequilibrium statistical operator method. It was shown that a soliton undergoes ...
A way to define the phase distribution for a single mode quantum field
(Journal of Physics. A: Mathematical and General, 1999)
The idea that the phase of single-mode field may be correctly defined as a phase difference between the state considered and a highly excited coherent state treated as the reference phase state, although present in discussions ...
Cation distribution and magnetic properties of ternary Zn2.33-xCO2Sb0.67O4 spinels
(Journal of Physics: Condensed Matter, 1996)
The series of spinels Zn2.33-xCoxSb0.67O4 (0.23 less than or equal to x less than or equal to 2.33) was prepared by ceramic technology. The crystal structures were refined from the x-ray diffraction data using the Rietveld ...
Effects of quantum lattice fluctuations on vibron pairing in two-site systems
(Physical Review B: Condensed Matter and Materials Physics, 1996)
The existence of a two-vibron (amide-I quanta) bound state has been examined within the framework of a two-site realization of the Davydov model. The parameter space of the system is divided into two regions where the ...
