Interactions, which only satisfy the ordinary second law on average. These second laws are not only relevant for small systems, butĪlso apply to individual macroscopic systems interacting via long-range In one regime one canĬause an apparent violation of the usual second law, through a process ofĮmbezzling work from a large system which remains arbitrarily close to its Transitions, depending on how cyclic the process is. Three regimes which determine which family of second laws govern state One, and show that they can never increase. Particular, we find a family of free energies which generalise the traditional Transformations are possible, but an entire family of constraints. Macroscopic scale, imposing not just one constraint on what state Law for microscopic systems takes on a very different form than it does at the Is there a second law of thermodynamics in this regime? Here, weįind that for processes which are cyclic or very close to cyclic, the second For example, if two blocks of metal at different temperatures are brought into thermal. That is, if the system is initially in a low-entropy (ordered) state, its condition will tend to slide spontaneously toward a state of maximum entropy (disorder). In the regime where we only have a small number of particles interacting with a The second law of thermodynamics states that, in a closed system, the entropy does not decrease. Interacting however, we are seeing that one can make sense of thermodynamics The second law applies to systems composed of many particles Its originalįormulation, due to Clausius, states that "Heat can never pass from a colder toĪ warmer body without some other change, connected therewith, occurring at the Statistically unlikely that they are effectively forbidden.
