On Lorentz and Einstein-Laub forces in material media
As a continuation of the discussion started in (M. Mansuripur, Phys. Rev. Lett. 108, 193901 (2012)), we show that the approach based on Lorentz force law in material media, like Einstein-Laub…

Vector Potential and Magnetic Field of Axially Symmetric Currents
A solution is proposed for finding the vector potential and magnetic field of any distribution of currents with axial symmetry. In this approach, the magnetic field and the vector potential are…

Difference-frequency generation in nonlinear scattering of acoustic waves by a rigid sphere
In this paper, the partial-wave expansion method is applied to describe the difference-frequency pressure generated in a nonlinear scattering of two acoustic waves with an arbitrary wavefront by…

Electromagnetic Angular Momentum and Relativity
Recently there have been suggestions that the Lorentz force law is inconsistent with special relativity. This is difficult to understand, since Einstein invented relativity in order to reconcile…

A partitioned model order reduction approach to rationalise computational expenses in multiscale fracture mechanics
We propose in this paper an adaptive reduced order modelling technique based on domain partitioning for parametric problems of fracture. We show that coupling domain decomposition and…

The Frieden-Soffer Extreme Physical Information Principle in a Non-extensive Setting
We show that the Frieden and Soffer's Extreme Physical Information principle, applied to a non-extensive statistical scenario, yields solutions to several well-known classical …

An Extended Dynamical Equation of Motion, Phase Dependency and Inertial Backreaction
Newton's second law has limited scope of application when transient phenomena are present. We consider a modification of Newton's second law in order to take into account a sudden change…

Two charges on plane in a magnetic field: special trajectories
A classical mechanics of two Coulomb charges on a plane (e1, m1) and (e2, m2) subject to a constant magnetic field perpendicular to a plane is considered. Special "superintegrable"…

Off-axial acoustic radiation force of pressor and tractor Bessel beams on a sphere
Acoustic Bessel beams are known to produce an axial radiation force on a sphere centered on the beam axis (on-axial configuration) that exhibits both "pressor" and "tractor"…

On the interaction of electromagnetic waves with conductors
We study the interaction of electromagnetic waves with electrons. Our results can be applied to radio waves in the ionosphere or to lasers impinging on metals causing melting. We generalize the…

Flute-like musical instruments: a toy model investigated through numerical continuation
Self-sustained musical instruments (bowed string, woodwind and brass instruments) can be modeled by nonlinear lumped dynamical systems. Among these instruments, flutes and flue organ pipes present…

External Tonehole Interactions in Woodwind Instruments
The classical Transfer-Matrix Method (TMM) is often used to calculate the input impedance of woodwind instruments. However, the TMM ignores the possible influence of the radiated sound from toneholes…
