Abstract:

We have calculated the linear in the magnetic-field contributions to the mean current , to the noise and for the third cumulant of equilibrium current fluctuations in a macroscopic inhomogeneous systems. The third cumulant for such systems appears to be non-zero. The obtained results satisfy the non-equilibrium fluctuation relation of Saito and Utsumi. Keywords:
