Magnetic polarons and magnetoresistance in EuB6
M. J. Calderon, L. G. L. Wegener, P. B. Littlewood
EuB6 is a low carrier density ferromagnet which exhibits large magnetoresistance, positive or negative depending on temperature. The formation of magnetic polarons just above the m…

Schrodinger equation with a spatially and temporally random potential: Effects of cross-phase modulation in optical communication
A. G. Green, P. B. Littlewood, P. P. Mitra +1
We model the effects of cross-phase modulation in frequency (or wavelength) division multiplexed optical communications systems, using a Schrödinger equation with a spatially and t…

Fluctuation induced hopping and spin polaron transport
L. G. L. Wegener, P. B. Littlewood
We study the motion of free magnetic polarons in a paramagnetic background of fluctuating local moments. The polaron can tunnel only to nearby regions of local moments when these f…
