The stationary state of a quantum particle strongly coupled to a quantum thermal bath is known to be non-Gibbsian, due to entanglement with the bath. For harmonic potentials, where the system can be described by effective temperatures, thermodynamic relations are shown to take a generalized Gibbsian form that may violate the Clausius inequality. For the weakly anharmonic case, a Fokker-Planck-type description is constructed. It is shown that then work can be extracted from the bath by cyclic… 
Thermodynamics and small quantum systems
Abstract Small quantum systems non-weakly coupled to a bath become in the quantum regime surrounded by a cloud of photons or phonons, which modifies their thermodynamic behaviour. Exactly solvable
Thermal machines beyond the weak coupling regime
How much work can be extracted from a heat bath using a thermal machine? The study of this question has a very long history in statistical physics in the weak-coupling limit, when applied to
The second law of thermodynamics in the quantum Brownian oscillator at an arbitrary temperature
Abstract.In the classical limit no work is needed to couple a system to a bath with sufficiently weak coupling strength (or with arbitrarily finite coupling strength for a linear system) at the same
Open Quantum Systems at Low Temperature
It is known that the origin of the deviations from standard thermodynamics proceed from the strong coupling to the bath. Here, it is shown that these deviations are related to the power spectrum of
Strong Coupling Corrections in Quantum Thermodynamics.
This work provides strong-coupling corrections to the second law applicable to general systems in three of its different readings: As a statement of maximal extractable work, on heat dissipation, and bound to the Carnot efficiency.
Thermodynamics of Quantum Information Systems — Hamiltonian Description
This work proves the formula within Hamiltonian description of drawing work from a quantum system and a heat bath, at the cost of entropy of the system, and derives Landauer's principle as a consequence of the second law within the considered model.
Landauer's principle in the quantum regime.
We demonstrate the validity of Landauer's erasure principle in the strong coupling quantum regime by treating the system-reservoir interaction in a thermodynamic way. We show that the initial
Does the second law hold in the quantum regime?
In this paper, our focus is on the question whether the cyclic process of coupling and decoupling of a charged quantum magneto-oscillator or a charged quantum electro-oscillator from a quantum heat
Thermodynamic control by frequent quantum measurements
M disturbances of thermal equilibrium between two-level systems (TLSs) and a bath are predicted, caused by frequent, brief quantum non-demolition measurements of the TLS energy states, allowing cooling and state purification over an interval much shorter than the time needed for thermal equilibration or for a feedback control loop.
Bath-generated work extraction and inversion-free gain in two-level systems
The spin–boson model, often used in NMR and ESR physics, quantum optics and spintronics, is considered in a solvable limit to model a spin one-half particle interacting with a bosonic thermal bath.

As shown in Sects. 3.1, 2 we can immediately obtain expectation values for processes described by the linear Langevin equations (3.1, 31). For nonlinear Langevin equations (3.67, 110) expectation
