What is the force at a spinning object, classically, relativistic and quantum mechanically?

Magus found a force on a spinning particle. It is a lift force that acts along a direction perpendicular to the particle linear velocity and its rotational velocity. Does it have a quantum...

Can we model a metal by a black-body at thermal Fermi temperature?

A black-body absorbs and re-emit radiations at all wavelengths. The intensity due to a black-body is due to Boltzmann-Stefan law. Metals are modeled by a system of free electrons. The uppermost...

Does light have mass inside a stationary and accelerating conductor?

Light is known to be massless in vacuum. However, when it enters a conductor, does it still have zero mass? In a transparent medium, the speed of light is less that c, which would imply that light...

Is there any relation between the de Broglie wavelength and the acceleration of the particle?

According to classical electrodynamics theory, an accelerating charged particle emits an electromagnetic radiation. Unruh on the other hand found that an accelerating observer (charge) will find...

Are the electric and magnetic fields of a freely moving charge always perpendicular to each other and to the particle velocity?

In electromagnetism, a free moving particle charged particle has its electric and magnetic fields perpendicular to each other, and to the particle velocity. Is this true even if the photon is...

Does an electric field applied on a moving electron create a torque?

A moving electron has both electric and magnetic fields that are perpendicular to its velocity direction. Does the electric field create a torque on the electron? If so what is that torque? Does...

Does the electron interact with its electric and magnetic dipoles with the electromagnetic fields simultaneously?

A single particle is known to have a zero dipole moment but a non-vanishing magnetic dipole moment. We have found that the electric dipole moment points along the velocity direction so it gives...
