Note added after Eq(42):
For charged systems, a small correction arises from the constraint of zero electrical current (zc) under a thermal
gradient. This correction can be included in the present formalism by using Onsager’s reciprocity relations, and leads
to modified expressions for Eq(18, 40 and 41). These may be written as
