It is well known in thermodynamics that the creation of correlations costs work. It seems then a truism that if a thermodynamic transformation A→B is impossible, so will be any transformation that in sending A to B also correlates among them some auxiliary systems C. Surprisingly, we show that this is not the case for nonequilibrium thermodynamics of microscopic systems. On the contrary, the creation of correlations greatly extends the set of accessible states, to the point that we can perform…

Correlations as a resource in quantum thermodynamics
It is proved that the work cost of generating multiple copies of a state is lower if the copies are correlated, pointing out at the irreversibility of the process in the single-shot regime.
By-passing fluctuation theorems
It is shown that there exist catalytic processes that lead to highly correlated work distributions, expected to have implications for stochastic and quantum thermodynamics.
Correlating Thermal Machines and the Second Law at the Nanoscale
Thermodynamics at the nanoscale is known to differ significantly from its familiar macroscopic counterpart: the possibility of state transitions is not determined by free energy alone, but by an
Fluctuating States: What is the Probability of a Thermodynamical Transition?
If the second law of thermodynamics forbids a transition from one state to another, then it is still possible to make the transition happen by using a sufficient amount of work. But if we do not have
Work and reversibility in quantum thermodynamics
It is a central question in quantum thermodynamics to determine how irreversible is a process that transforms an initial state $\rho$ to a final state $\sigma$, and whether such irreversibility can
Energetic instability of passive states in thermodynamics
It is shown that an optimal amount of energy can be extracted from any athermal quantum state when using a machine that operates in a reversible cycle.
Continuous thermomajorization and a complete set of laws for Markovian thermal processes
The standard dynamical approach to quantum thermodynamics is based on Markovian master equations describing the thermalization of a system weakly coupled to a large environment, and on tools such as
Fundamental work cost of quantum processes
Information-theoretic approaches provide a promising avenue for extending the laws of thermodynamics to the nanoscale. Here, we provide a general fundamental lower limit, valid for systems with an
Von Neumann Entropy from Unitarity.
This Letter shows that the von Neumann entropy fully characterizes single-shot state transitions in unitary quantum mechanics, as long as one has access to a catalyst-an ancillary system that can be reused after the transition- and an environment which has the effect of dephasing in a preferred basis.

The resource theory approach is a recently developed framework used in the study of thermodynamics for finite sized quantum systems. A simple way to describe how a quantum system evolves under


The second laws of quantum thermodynamics
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.

The conclusion is that it is generally not possible to find a unique entropy that has all relevant physical properties, but it is shown that one can define two entropy functions, called S− and S+, which, taken together, delimit the range of adiabatic processes that can occur between non-equilibrium states.
A measure of majorization emerging from single-shot statistical mechanics
It is shown that an expression that quantifies majorization determines the optimal guaranteed work, and it is argued it should be the central quantity of statistical mechanics, rather than the von Neumann entropy.
Resource theory of quantum states out of thermal equilibrium.
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 work value of information
This work derives strikingly simple expressions for the extractable work in the extreme cases of effectively zero- and arbitrary risk tolerance respectively, thereby enveloping all cases and making a connection between heat engines and the smooth entropy approach.
Work extraction and thermodynamics for individual quantum systems.
It is proved that the second law of thermodynamics holds in this framework, and a simple protocol is given to extract the optimal amount of work from the system, equal to its change in free energy.
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.
Limits to catalysis in quantum thermodynamics
Quantum thermodynamics is a research field that aims at fleshing out the ultimate limits of thermodynamic processes in the deep quantum regime. A complete picture of thermodynamical processes
