Is it true that the second law of thermodynamics is asymmetric with respect to time reversal?

Yes. The second law of thermodynamics inherently describes macroscopic irreversibility and the increase of entropy, representing an asymmetry under time reversal.

The analysis

The retrieved papers provide robust support for the claim that the second law of thermodynamics and its entropic increase are associated with time-reversal asymmetry (an arrow of time). Papers explicitly link time-reversal asymmetry of path probabilities or dynamics to entropy production and the second law. No papers refute this fundamental thermodynamic principle.
