Channeling of protons through carbon nanotubes
(Journal of Physics: Conference Series, 2008)
We investigate how dynamic polarization of carbon valence electrons influences both the angular and spatial distributions of protons channeled in a (11, 9) single-wall carbon nanotube placed in vacuum and in different ...
Design of Li phosphorous doped bronzes obtained by using spray pyrolysis
(Journal of Physics: Conference Series, 2008)
The ultrasonic spray pyrolysis technique has been, during last three decades, one of the major techniques of synthesis a wide variety of materials. One of the most important among the ionic conductors is lithium phosphorous ...
Wake effect in graphene due to moving charged particles
(Journal of Physics: Conference Series, 2014)
We study the wake effect in a supported graphene layer induced by external charged particles moving parallel to it by using the dynamic polarization function of graphene within the random phase approximation for its pi ...
Interactions of ions with graphene
(Journal of Physics: Conference Series, 2010)
We evaluate the stopping and image forces on a charged particle moving parallel to a single sheet of graphene supported by an insulating substrate under the gating conditions. The forces are presented as functions of the ...
Local and electronic structure around manganese in Cd0.98Mn0.02Te0.97Se0.03 studied by XAFS
(Journal of Physics: Conference Series, 2013)
X-ray Absorption Fine Structure (XAFS) technique was employed to study local electronic and structural features of Mn ions incorporated in Cd0.98Mn0.02Te0.97Se0.03. XAFS measurements performed at Mn K edge revealed that ...
Vibron Self-trapped States in Biological Macromolecules: Comparison of Different Theoretical Approaches
(Journal of Physics: Conference Series, 2012)
We present a study of the applicability of the variational treatments based on using of the modified Lang-Firsov unitary transformation (MLF method) in the investigation of the vibron self-trapped states in biological ...
Charge transport in the alpha-helix proteins
(Journal of Physics: Conference Series, 2010)
In this paper we investigate charge transport in the alpha-helix proteins. It is considered that charge carriers are partially dressed small polarons, that are formed by electron self-trapping in the weak coupling limit. ...
Vibron properties in quasi 1D molecular structures: the case of two parallel unshifted macromolecuar chains
(Journal of Physics: Conference Series, 2016)
We study the hopping mechanism of the vibron excitation transport in the system of two parallel unshifted 1D macromolecuar chains in the framework of non-adiabatic polaron theory. We suppose that the vibron interaction ...
Temperature effects on fidelity of reflection from absorbing Bragg mirrors
(Journal of Physics: Conference Series, 2016)
In the paper, we consider the quantum effects in reflection of the electromagnetic field from an absorbing Bragg mirror. The special emphasis is placed on the study of the influence of thermal noises of the mirror environment ...
Non-entire functions of creation and annihilation operators and their relation to phase operator
(Journal of Physics: Conference Series, 2006)
On the coherent states vertical bar alpha GT any entire function of creation and annihilation operators may be defined. We show that it is not the case for non-entire functions. Use of vertical bar alpha GT LT alpha vertical ...
