| Popis: | We introduce a novel perspective on Newton's Law of Cooling by framing it within the context of information geometry. By characterizing it as a specific representation of a gradient flow, we establish a connection with the well-known Horse-Carrot Theorem and reveal previously unexplored instances of asymmetric relaxations in the context of endoreversible processes. We present a completely general and practical criterion for predicting asymmetries based on the Amari-Chentsov tensor, whose applicability extends to both classical and quantum thermodynamics. Illustrative examples include faster cooling down of quantum ideal gases, and relaxations reminiscent of the Mpemba effect in classical ideal gases. Comment: 14 pages, 3 figures |
