Abstract: | This paper concerns the properties of a symmetric barrier between two reservoirs. The barrier can passK conserved quantities. The current of theith quantity is assumed to satisfy the nonlinear relationJ
i=A
ij![Delta](/content/n07154v62t855005/xxlarge916.gif) j+Bijkl![Delta](/content/n07154v62t855005/xxlarge916.gif) j![Delta](/content/n07154v62t855005/xxlarge916.gif) k![Delta](/content/n07154v62t855005/xxlarge916.gif) l where the ![Delta](/content/n07154v62t855005/xxlarge916.gif) i's are the affinity differences across the barrier andA
ij andB
ijkl are functions of the average affinities of the reserviors. It is shown thatB
ijkl is symmetric in all indices. |
