"A calorie is a calorie" violates the second law of thermodynamics
Nutrition Journal, 2004 The principle of "a calorie is a calorie," that weight change in hypocaloric diets is independent of macronutrient composition, is widely held in the popular and technical literature, and is frequently justified by appeal to the laws of thermodynamics ...

Quantum thermodynamically consistent local master equations
Physical Review Research, 2021 Local master equations are a widespread tool to model open quantum systems, especially in the context of many-body systems. These equations, however, are believed to lead to thermodynamic anomalies and violation of the laws of thermodynamics. In contrast,

Advanced Engineering Materials, EarlyView.This study investigates the complex mechanics of individual electrospun polycaprolactone fibers under small and large strains. Combining experiments with a visco‐hyperelastic damage model, this work reveals and quantifies these fibers’ nonlinear behavior, including strain‐stiffening, viscoelasticity, and damage.

Zeroth and Second Laws of Thermodynamics Simultaneously Questioned in the Quantum Microworld
, 2000 Several models of quantum open systems are known at present to violate, according to principles of the standard quantum theory of open systems, the second law of thermodynamics. Here, a new and rather trivial model of another type is suggested describing

Compatibility of linear-response theory with the second law of thermodynamics and the emergence of negative entropy production rates [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2019 The reliability of physical theories depends on whether they agree with well-established physical laws. In this work, we address the compatibility of the Hamiltonian formulation of linear-response theory with the second law of thermodynamics. In order to

Robustness of the second law of thermodynamics under generalizations of the maximum entropy method
, 2007 It is shown that the laws of thermodynamics are extremely robust under generalizations of the form of entropy. Using the Bregman-type relative entropy, the Clausius inequality is proved to be always valid.
