Conservation Laws and Thermodynamic Efficiencies
Giuliano Benenti, Giulio Casati, Jiao Wang
TL;DR
This paper demonstrates that systems with a single conserved quantity can achieve Carnot efficiency in the thermodynamic limit, supported by a model of elastically colliding particles.
Contribution
It establishes a general theoretical link between conservation laws and maximum thermodynamic efficiency, illustrated through a specific particle chain model.
Findings
Systems with one conserved quantity reach Carnot efficiency asymptotically.
The diatomic chain model exemplifies the theoretical result.
Conservation laws critically influence thermodynamic limits.
Abstract
We show that generic systems with a single relevant conserved quantity reach the Carnot efficiency in the thermodynamic limit. Such a general result is illustrated by means of a diatomic chain of hard-point elastically colliding particles where the total momentum is the only relevant conserved quantity.
