Abstract
This paper shows that Onsager reciprocal relations remain valid even in presence of a generic magnetic field so that the time reversal symmetry is broken. The authors prove that breaking the time reversal symmetry does not remove the thermodynamic constraints imposed by the Onsager relations on heat to work conversion. In particular, the possibility of an engine operating at the Carnot efficiency with finite power is ruled out on purely thermodynamic grounds
Highlights
Onsager reciprocal relations [1,2,3] are a cornerstone in nonequilibrium statistical physics
We provide analytical and numerical evidence that Onsager reciprocal relations remain valid for systems with broken time-reversal symmetry as is typically the case when a generic magnetic field is present
Our results show that the Onsager reciprocal relations are much more general than previously assumed

We provide analytical and numerical evidence that Onsager reciprocal relations remain valid for systems with broken time-reversal symmetry as is typically the case when a generic magnetic field is present. Our results show that the Onsager reciprocal relations are much more general than previously assumed. The fundamental constraints they impose on heat to work conversion remain valid with broken time-reversal symmetry. The possibility of an engine operating at the Carnot efficiency with finite power is ruled out on purely thermodynamic grounds
