Singularity-Free Electrodynamics for Point Charges and Dipoles: Classical Model for Electron Self-Energy and Spin [PDF]

, 2002
It is shown how point charges and point dipoles with finite self-energies can be accomodated into classical electrodynamics. The key idea is the introduction of constitutive relations for the electromagnetic vacuum, which actually mirrors the physical ...

Modeling and evaluation of magnetic fluid deformable mirror with dual-layer actuators

International Journal of Optomechatronics, 2019
In this paper, a rectangular magnetic fluid deformable mirror (MFDM) with dual-layer actuators is proposed, which is designed to improve the correction performance for full-order aberrations.

Hydrogen atom in crossed electric and magnetic fields: Phase space topology and torus quantization via periodic orbits [PDF]

, 2006
A hierarchical ordering is demonstrated for the periodic orbits in a strongly coupled multidimensional Hamiltonian system, namely the hydrogen atom in crossed electric and magnetic fields.

Measuring the LISA test mass magnetic proprieties with a torsion pendulum [PDF]

, 2004
Achieving the low frequency LISA sensitivity requires that the test masses acting as the interferometer end mirrors are free-falling with an unprecedented small degree of deviation.

Single-light-source three-axis atomic magnetometer based on orthogonal and non-overlapping dual-pump beams

Results in Physics, 2023
In this paper, we propose a three-axis atomic magnetometer (AM), in which one light beam is divided into two orthogonal spatially separated pump beams by a lateral displacement polarized beam splitter and reflector mirrors; this scheme suppresses the ...

Small scale energy release driven by supergranular flows on the quiet Sun [PDF]

, 2007
In this article we present data and modelling for the quiet Sun that strongly suggest a ubiquitous small-scale atmospheric heating mechanism that is driven solely by converging supergranular flows. A possible energy source for such events is the power

Enhancement of the Magneto-Optical Kerr Effect in One- Dimensional Magnetophotonic Crystals with Adjustable Spatial Configuration [PDF]

Journal of Optoelectronical Nanostructures, 2019
We studied magnetophotonic crystals (MPCs) with introduced magneticdefect layer sandwiched between magnetic and dielectric Bragg mirrors. Thesemagnetophotonic crystals have excellent capabilities to enhance reflection and Kerrrotation simultaneously.

More on Meta-Stable Brane Configuration [PDF]

, 2007
We describe the intersecting brane configuration of type IIA string theory corresponding to the meta-stable nonsupersymmetric vacua in four dimensional N=1 supersymmetric SU(N_c) gauge theory with an antisymmetric flavor, a conjugate symmetric flavor ...

Spatially selective excitation of spin dynamics in magneto-photonic crystals by spectrally tunable ultrashort laser pulses

Nanophotonics, 2022
In this work, we tackle the problem of the spatially selective optical excitation of spin dynamics in structures with multiple magnetic layers. The 120 fs circularly polarized laser pulses were used to launch magnetization precession in an all-dielectric
