Fractional angular momentum in cold-atom systems.

The quantum statistics of bosons or fermions are manifest through the even or odd relative angular momentum of a pair. We show theoretically that, under certain conditions, a pair of certain test particles immersed in a fractional quantum Hall state possesses, effectively, a fractional relative angular momentum, which can be interpreted in terms of fractional braid statistics. We propose that t...

Equations of Motion of Systems with Internal Angular Momentum

The angular momentum of a many-particle system with respect to its centre of mass is known as the ”internal angular momentum” and is a property of the system that is independent of the observer. Internal angular momentum is therefore and attribute that characterizes a system in the same way as its mass or charge. In the case of a rigid body and particularly in the case of an elementary particle...
