# A general derivation and quantification of the third law of thermodynamics

@article{Masanes2017AGD, title={A general derivation and quantification of the third law of thermodynamics}, author={Lluis Masanes and Jonathan Oppenheim}, journal={Nature Communications}, year={2017}, volume={8} }

The most accepted version of the third law of thermodynamics, the unattainability principle, states that any process cannot reach absolute zero temperature in a finite number of steps and within a finite time. Here, we provide a derivation of the principle that applies to arbitrary cooling processes, even those exploiting the laws of quantum mechanics or involving an infinite-dimensional reservoir. We quantify the resources needed to cool a system to any temperature, and translate these…

A set of laws for general quantum resource theories, which generalise the laws of thermodynamics are derived, which first test on thermodynamics with multiple conservation laws, and then apply to the theory of local operations under energetic restrictions.

A Resource Theory for Work and Heat

This work proposes a resource theory of quantum thermodynamics without a background temperature, so that no states at all come for free, and applies this resource theory to the case of many non-interacting systems, and shows that states are classified by their entropy and average energy.

Here, it is found that for processes which are approximately cyclic, the second law for microscopic systems takes on a different form compared to the macroscopic scale, imposing not just one constraint on state transformations, but an entire family of constraints.

Fundamental limitations for quantum and nanoscale thermodynamics.

It is found that there are fundamental limitations on work extraction from non-equilibrium states, owing to finite size effects and quantum coherences, which implies that thermodynamical transitions are generically irreversible at this scale.

It is found that coherences over energy levels must decay at rates that are suitably adapted to the transition rates between energy levels, and it is shown that the limitations are matched in the case of a single qubit, in which case the full characterization of state-to-state transformations is obtained.

It is shown that the free energy of thermodynamics emerges naturally from the resource theory of energy-preserving transformations, provided that a sublinear amount of coherent superposition over energy levels is available, a situation analogous to the sub linear amount of classical communication required for entanglement dilution.

The many, severe constraints of microscopic thermodynamics are reduced to the sole requirement that the nonequilibrium free energy decreases in the transformation, which shows that, in principle, reliable extraction of work equal to the free energy of a system can be performed by microscopic engines.
