Scattering of generalized Bessel beams simulated with the discrete dipole approximation
Journal of Physics: Conference Series, 2021 We consider the simulation of scattering of the high-order vector Bessel beams in the discrete dipole approximation framework (DDA). For this purpose, a new general classification of all existing Bessel beam types was developed based on the superposition

Two-Grating Talbot Bands Spectral Domain Interferometer [PDF]
, 2015 A configuration for Talbot bands is presented, where two tilted gratings replace the splitter normally used for recombining the signals from the two interferometer arms.

Electron vortex beams in a magnetic field: A new twist on Landau levels and Aharonov-Bohm states
, 2012 We examine the propagation of the recently-discovered electron vortex beams in a longitudinal magnetic field. We consider both the Aharonov-Bohm configuration with a single flux line and the Landau case of a uniform magnetic field.

Coherent full polarization control based on bound states in the continuum
Nature Communications, 2022 Bound states in the continuum (BICs) are resonant modes of open structures that do not suffer damping, despite being compatible with radiation in terms of their momentum.

The gravitational interaction of light: from weak to strong fields [PDF]
, 1998 An explanation is proposed for the fact that pp-waves superpose linearly when they propagate parallely, while they interact nonlinearly, scatter and form singularities or Cauchy horizons if they are antiparallel.

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.

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.

Deep learning-assisted light sheet holography.
Optics Express, 2023 In a novel approach to layer-based holography, we propose a machine learning-assisted light sheet holography-an optimized holography technique which projects a target scene onto sheets of light along the longitudinal planes (i.e.

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.

Spontaneous symmetry breaking in spinor Bose-Einstein condensates [PDF]
, 2013 We present an analytical model for the theoretical analysis of spin dynamics and spontaneous symmetry breaking in a spinor Bose-Einstein condensate (BEC).
