Аннотация: Electrodynamic analysis of plasma oscillations in a spherical metal nanoparticle is performed. It is shown that typical reduction in the frequency and quality factor of the resonances with increasing nanoparticle radius fades if the mode number grows. Depending on the particle radius, the resonant enhancement of the electric field might considerably either increase or decrease with increasing mode number. (C) 2016 Wiley Periodicals, Inc.

Аннотация: We consider light-induced binding and motion of dielectric microparticles in an optical waveguide that gives rise to a backaction effect such as light transmission oscillating with time. Modeling the particles by dielectric slabs allows us to solve the problem analytically and obtain a rich variety of dynamical regimes both for Newtonian and damped motion. This variety is clearly reflected in temporal oscillations of the light transmission. The characteristic frequencies of the oscillations are within the ultrasound range of the order of 105 kHz for micron-size particles and injected power of the order of 100mW. In addition, we consider dynamics of a dielectric particle, driven by light propagating inside a Fabry-Perot resonator. These phenomena pave a way for optical driving and monitoring of the motion of particles in waveguides and resonators.

Аннотация: We analyze the energy spectrum and eigenstates of cold atoms in a tilted brick-wall optical lattice. When the tilt is applied, the system exhibits a sequence of topological phase transitions reflected in an abrupt change of the eigenstates. It is demonstrated that these topological phase transitions can be easily detected in a laboratory experiment by observing Bloch oscillations of cold atoms.

Аннотация: We analyzemicroscopic models of the particle source or sink which consist of a one- or two-site Bose-Hubbard model (the system) weakly coupled to amany-site Bose-Hubbard model (the reservoir). Assuming unequal filling factors for the system and reservoir, we numerically study equilibration dynamics and compare it with the solution of the master equation on the reduced density matrix of the system. Necessary conditions for the validity of the master equation approach are formulated.

Аннотация: We investigate the optical transmission of a monochromatic laser beam passing through an individual domain of a nematic liquid crystal formed by the polycarbonate surface. The domain has the radial orientation structure with a disclination line on the polymer surface, which gradually transforms to "pseudoplanar" alignment at the coherence distance ? from the surface. The dependence of the optical transmittance on an electric field applied to the domain are different at various light polarization directions relative to the disclination lines and, in the absence of an analyzer, are accompanied by interference oscillations. To explain the results obtained, a domain is considered to be a gradient lens with the refractive index variable in the plane perpendicular to the laser beam and the resulting deflecting effect that was collected at the beam path through the liquid crystal layer. © 2016 Optical Society of America.

Аннотация: We study the frequency doubling in a quadratic nonlinear photonic crystal consisting of periodically poled structures mediated by uniform layers with random lengths. These structures can be formed by new local impact methods for ferroelectric crystal structuring. The statistical frequency doubling theory is developed for such structures. The effect of the number of random layers and variation in their thicknesses on the second-harmonic conversion efficiency is clarified. It is demonstrated that a proper choice of the intermediate layer thickness can enhance or suppress the conversion efficiency. A new type of the Makerfringes-like second-harmonic intensity oscillations is predicted. © 2017 Optical Society of America.

Аннотация: We have discovered oscillations of the Faraday rotation asa function of the thickness of Pd layers in Co/Pd multilayer films. A correlation is traced between the behavior of the Faraday relation as a function of the thickness of the Pd layers and the magnitude of the saturation field determined from the field dependences of the Faraday rotation.

Аннотация: Changes in the electronic structure in the normal phase of high-T-c superconductors (HTSCs), viz., layered cuprates, are considered. The results of LDA + GTB calculations of the electron structure and the Fermi surface of La2-xSrxCuO4 one-layer cuprates with allowance for strong correlations are compared with ARPES and quantum oscillations data. Two critical points x(c1) and x(c2) are discovered at which the rearrangement of the Fermi surface takes place. In the vicinity of these points, changes in the thermodynamic properties at low temperatures are determined using the Lifshits ideology concerning 2.5-order quantum phase transitions. A singularity delta(C/T) proportional to (x-x(e))(1/2) in the electron heat capacity agrees well with the available experimental data in the vicinity of x(c1)approximate to 0.15. Sign reversal of the Hall constant upon doping is also considered qualitatively.

Аннотация: We consider the motion of ballistic electrons in a miniband of a semiconductor superlattice (SSL) under the influence of an external, time-periodic electric field. We use a semiclassical, balance-equation approach, which incorporates elastic and inelastic scattering (as dissipation) and the self-consistent field generated by the electron motion. The coupling of electrons in the miniband to the self-consistent held produces a cooperative nonlinear oscillatory mode which, when interacting with the oscillatory external field and the intrinsic Bloch-type oscillatory mode, can lead to complicated dynamics, including dissipative chaos. For a range of values of the dissipation parameters we determine the regions in the amplitude-frequency plane of the external field in which chaos can occur. Our results suggest that for terahertz external fields of the amplitudes achieved by present-day free-electron lasers, chaos may be observable in SSL's. We clarify the nature of this interesting nonlinear dynamics in the superlattice-external-field system by exploring analogies to the Dicke model of an ensemble of two-level atoms coupled with a resonant cavity field, and to Josephson junctions.

Заглавие : Switching nano-device based on rabi oscillations
Место публикации : Phys. Lett. A. - 1994. - Vol. 196, Is. 1-2. - P.65-69. - ISSN 0375-9601, DOI 10.1016/0375-9601(94)91045-6
Примечания : Cited References: 5
Аннотация: We describe a switching device based on Rabi oscillations. The device consists of a well region separated from a free region by a potential barrier. The potential landscape is adjusted so that one bound state and one quasi level are present. By applying a microwave field with a driving frequency close to the separation between the two levels, a particle initially in the ground state can be activated to the quasi-level, and subsequently tunnel to the free region. The probability for tunneling in the free region exhibits a plateau structure, as the wave function is emitted by bursts after each Rabi oscillation. The leakage current can then be controlled by varying the amplitude of the external field, the barrier height/width, and the frequency mismatch.
