Entropy, inflation and the arrow of time

Classical and Quantum Gravity, 1991
One of the motivations for the introduction of inflation was to explain the large entropy of the observed Universe. Penrose has recently pointed out that the entropy of the observable Universe is small when compared with the maximal possible entropy. The authors show that this phenomenon is also a natural consequence of inflation.

Transfer entropy in physical systems and the arrow of time

Physical Review E, 2016
Recent developments have cemented the realization that many concepts and quantities in thermodynamics and information theory are shared. In this paper, we consider a highly relevant quantity in information theory and complex systems, the transfer entropy, and explore its thermodynamic role by considering the implications of time reversal upon it.
