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...

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...

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...
