Lorentz force electrical impedance tomography [PDF]

open access: yesIRBM, 2013
This article describes a method called Lorentz Force Electrical Impedance Tomography. The electrical conductivity of biological tissues can be measured through their sonication in a magnetic field: the vibration of the tissues inside the field induces an electrical current by Lorentz force. This current, detected by electrodes placed around the sample,

Magnetic monopoles and Lorentz force

open access: yes, 2001
The formulation of a generalized classical electromagnetism that includes both electric and magnetic charges, is explored in the framework of two potential approach. It is shown that it is possible to write an action integral from which one can derive, by least action principle, the symmetrized set of Maxwell's equations, but also the Lorentz force law

The ponderomotive Lorentz force [PDF]

open access: yesNonlinearity, 2020
This paper describes a curious phenomenon: a particle in a rapidly varying potential is subject to an effective magnetic-like force. This force is in addition to the well-known ponderomotive force, but it has not been shown to exist before except for the linear case of a rapidly rotating quadratic saddle potential.

Stationary state in Brownian systems with Lorentz force

open access: yesPhysical Review Research, 2020
In systems with overdamped dynamics, the Lorentz force reduces the diffusivity of a Brownian particle in the plane perpendicular to the magnetic field. The anisotropy in diffusion implies that the Fokker-Planck equation for the probability distribution ...

Revealing photonic Lorentz force as the microscopic origin of topological photonic states

open access: yesNanophotonics, 2020
Charged particles like electrons moving in a magnetic field encounter Lorentz force, which governs the formation of electronic topological edge states in quantum Hall effect systems. Here we show that photons transporting in magneto-optical materials and

Topological thermal Hall effect for topological excitations in spin liquid: Emergent Lorentz force on the spinons

open access: yesSciPost Physics Core, 2020
We study the origin of Lorentz force on the spinons in a U(1) spin liquid. We are inspired by the previous observation of gauge field correlation in the pairwise spin correlation using the neutron scattering measurement when the Dzyaloshinskii-Moriya ...

Unveiling the Mechanism for the Rapid Acceleration Phase in a Solar Eruption

open access: yesThe Astrophysical Journal Letters, 2023
Two major mechanisms have been proposed to drive the solar eruptions: the ideal magnetohydrodynamic instability and the resistive magnetic reconnection. Due to the close coupling and synchronicity of the two mechanisms, it is difficult to identify their ...

Relativistic Spinor Dynamics Inducing the Extended Lorentz-Force-Like Equation [PDF]

open access: yes, 2004
The special relativistic dynamical equation of the Lorentz force type can be regarded as a consequence of a succession of space-time dependent infinitesimal Lorentz transformations as shown by one of us \cite{buitrago} and discussed in the introduction ...

Investigations on the Effects of Vortex-Induced Vibration with Different Distributions of Lorentz Forces

open access: yesApplied Sciences, 2017
The control of vortex-induced vibration (VIV) in shear flow with different distributions of Lorentz force is numerically investigated based on the stream function–vorticity equations in the exponential-polar coordinates exerted on moving cylinder for Re =
