Transient vibration analysis of a completely free plate using modes obtained by Gorman's superposition method [PDF]

, 2010
This paper shows that the transient response of a plate undergoing flexural vibration can be calculated accurately and efficiently using the natural frequencies and modes obtained from the superposition method.

Geometric phases, gauge symmetries and ray representation [PDF]

, 2006
The conventional formulation of the non-adiabatic (Aharonov-Anandan) phase is based on the equivalence class $\{e^{i\alpha(t)}\psi(t,\vec{x})\}$ which is not a symmetry of the Schr\"{o}dinger equation.

On the dragging of light by a rotating medium [PDF]

, 2007
When light is passing through a rotating medium the optical polarization is rotated. Recently, it has been reasoned that this rotation applies also to the transmitted image.

Common topological charge of several similar off-axis vortex light beams of arbitrary rotationally symmetric shape

Компьютерная оптика
We investigate the topological charge of superposition of parallel identical vortex beams of arbitrary shape – either Laguerre-Gaussian beams or Bessel-Gaussian beams or some other vortex beams with a rotationally symmetric intensity distribution.

Theory and applications of free-electron vortex states

, 2017
Both classical and quantum waves can form vortices: with helical phase fronts and azimuthal current densities. These features determine the intrinsic orbital angular momentum carried by localized vortex states.

A New Method to Measure the Electron Beam Energy Spectrum [PDF]

مجله علوم و فنون هسته‌ای, 2014
An innovative method has been used to calculate electron beam energy spectrum using depth-dose curve. The depth-dose distributions of the electron beam with different primary energies emerging from the electron accelerator were measured in water phantom ...

Creating an Array of Parallel Vortical Optical Needles

Photonics
We propose a method for creating parallel Bessel-like vortical optical needles with an arbitrary axial intensity distribution via the superposition of different cone-angle Bessel vortices.

Quantum interference in optical fields and atomic radiation

, 2001
We discuss the connection between quantum interference effects in optical beams and radiation fields emitted from atomic systems. We illustrate this connection by a study of the first- and second-order correlation functions of optical fields and atomic ...
