Interrogating imaginary optical force by the complex Maxwell stress tensor theorem [PDF]

open access: yesLight: Science & Applications, 2023
The complex Maxwell stress tensor theorem has been developed to relate the imaginary optical force, reactive strength of canonical momentum and total optical force of a nanoparticle, which is essential to perfect optical force efficiency.

The complex Maxwell stress tensor theorem: The imaginary stress tensor and the reactive strength of orbital momentum. A novel scenery underlying electromagnetic optical forces [PDF]

open access: yesLight: Science & Applications, 2022
The imaginary Maxwell stress tensor IMST and the reactive strength of orbital momentum ROM are established. It is shown that they universally produce reactive electromagnetic forces ILFs that counteract all currently observed time-averaged optical forces

Electromagnetic Force and the Maxwell Stress Tensor in Condensed Systems

open access: yes, 2000
While the electromagnetic force is microscopically simply the Lorentz force, its macroscopic form is more complicated, and given by expressions such as the Maxwell stress tensor and the Kelvin force.

Compact objects in conformal nonlinear electrodynamics

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
In this paper we consider a special case of vacuum nonlinear electrodynamics with a stress–energy tensor conformal to the Maxwell theory. Distinctive features of this model are the absence of a dimensional parameter for the nonlinearity description and a

Einstein–Cartan–Dirac gravity with U(1) symmetry breaking [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
Einstein–Cartan theory is an extension of the standard formulation of General Relativity where torsion (the antisymmetric part of the affine connection) is non-vanishing.

Computation of electromagnetic force densities: Maxwell stress tensor vs. virtual work principle

open access: yesJournal of Computational and Applied Mathematics, 2004
Authors' ummary: A couple of fundamental formulae are demonstrated in this paper, which allow a systematic algebraic derivation of local electromagnetic forces in any material, starting from the expression of the energy density of that material. The derivation can be achieved in terms of vector and tensor analysis notions exclusively, provided the ...

Dynamics of the optical forces in nanosystems [PDF]

open access: yesEPJ Web of Conferences, 2022
We investigate optical forces in the time domain, instead of using the time-average Maxwell stress tensor. We demonstrate first that a plane wave causes on a physical object an optical pressure that fluctuates at optical frequency in the time domain. The

The force density in electrical machines modeled as tension and pressure gradients of magnetic field lines

open access: yesAIP Advances, 2023
This paper shows how to model the force density in electrical machines based on the field lines of the magnetic flux density. The force density is written as two vector components: the magnetic tension force and the magnetic pressure gradient force. This
