Experimental observation of optical rotation generated in vacuum by a magnetic field.

We report the experimental observation of a light polarization rotation in vacuum in the presence of a transverse magnetic field. Assuming that data distribution is Gaussian, the average measured rotation is (3.9 +/- 0.5) x 10(-12) rad/pass, at 5 T with 44 000 passes through a 1 m long magnet, with lambda = 1064 nm. The relevance of this result in terms of the existence of a light, neutral, spin-zero particle is discussed.

Exactly solved dynamics for an infinite-range spin system.

It is well known that the dynamical evolution of a system of N spins can be viewed as a walk along the edges of an N-dimensional hypercube. I use this correspondence in an infinite-range spin system to derive a diffusion equation for the magnetization. The diffusion equation then leads to an ordinary differential equation that describes the time evolution of the magnetization for any given initial condition, and it is used to derive both static and dynamic properties of the spin system.
