With a class of quantum heat engines which consists of two-energy-eigenstate systems undergoing, respectively, quantum adiabatic processes and energy exchanges with heat baths at different stages of a cycle, we are able to clarify some important aspects of the second law of thermodynamics. The quantum heat engines also offer a practical way, as an alternative to Szilard's engine, to physically realize Maxwell's demon. While respecting the second law on the average, they are also capable of… 
Quantum heat engines, the second law and Maxwell's daemon
Abstract.We introduce a class of quantum heat engines which consists of two-energy-eigenstate systems, the simplest of quantum mechanical systems, undergoing quantum adiabatic processes and energy
Quantum heat engine beyond the adiabatic approximation
We introduce a new quantum heat engine, in which the working medium undergoes quantum quasi-adiabatic and non-unitary processes to extract work in the cycle. Two kinds of working medium are
Quantum thermodynamic cycles and quantum heat engines.
The role of Maxwell's demon is discussed and it is found that there is no violation of the second law, even in the existence of such a demon, when the demon is included correctly as part of the working substance of the heat engine.
Quantum heat engine with multilevel quantum systems.
By reformulating the first law of thermodynamics in the fashion of quantum-mechanical operators on the parameter manifold, we propose a universal class of quantum heat engines (QHE) using the
Quantum cooling by unitary transformations
We study the unitary time evolution of a simple quantum Hamiltonian describing a heat engine coupled to two heat baths. The engine is modeled as a three-level system. Each heat bath consists of a

This work suggests that the measurement postulate of quantum mechanics is intricately connected to the second law of thermodynamics, and challenges the conventional approach of simply quantifying quantum correlations as a thermodynamic work deficit.
Experimental Characterization of a Spin Quantum Heat Engine.
A quantum heat engine based on a spin-1/2 system and nuclear magnetic resonance techniques is experimentally implemented, able to reach an efficiency for work extraction very close to its thermodynamic limit.
Quantum heat engine cycle working with a strongly correlated electron system
A new model of a quantum heat engine (QHE) cycle is established, in which the working substance consists of an interacting electrons system. One of our purposes is to test the validity of the second
The Second Law of Thermodynamics in a Quantum Heat Engine Model
The second law of thermodynamics has been proven by many facts in classical world. Is there any new property of it in quantum world? In this paper, we calculate the change of entropy in T.D. Kieu's
Efficiency large deviation function of quantum heat engines
The efficiency of small thermal machines is typically a fluctuating quantity. We here study the efficiency large deviation properties of two exemplary quantum heat engines, the harmonic oscillator


Quantum-mechanical Maxwell’s demon
A Maxwell's demon is a device that gets information and trades it in for thermodynamic advantage, in apparent (but not actual) contradiction to the second law of thermodynamics. Quantum-mechanical
Extracting Work from a Single Heat Bath via Vanishing Quantum Coherence
We present here a quantum Carnot engine in which the atoms in the heat bath are given a small bit of quantum coherence. The induced quantum coherence becomes vanishingly small in the high-temperature
Quantum mechanical Carnot engine
A cyclic thermodynamic heat engine runs most efficiently if it is reversible. Carnot constructed such a reversible heat engine by combining adiabatic and isothermal processes for a system containing
A simple quantum heat engine
Quantum heat engines employ as working agents multi-level systems instead of gas-filled cylinders. We consider particularly two-level agents such as electrons immersed in a magnetic field. Work is
Statistical mechanical derivation of the second law of thermodynamics
In a macroscopic (quantum or classical) Hamiltonian system, we prove the second law of thermodynamics in the forms of the minimum work principle and the law of entropy increase, under the assumption
Mathematical Foundations of Quantum Mechanics
Mathematical Foundations of Quantum Mechanics was a revolutionary book that caused a sea change in theoretical physics. Here, John von Neumann, one of the leading mathematicians of the twentieth

The optimal performance of the engine when the cold bath is approaching absolute zero is studied and it is found that the optimal cooling rate converges linearly to zero when the temperature approaches absolute zero.
Thermodynamical proof of the Gibbs formula for elementary quantum systems
An elementary derivation is given of the formula for the thermal equilibrium states of quantum systems that can be described in finite-dimensional Hilbert spaces. The three assumptions made,
Enhancing Otto‐mobile Efficiency via Addition of a Quantum Carnot Cycle
It was shown recently that one can improve the efficiency of the Otto cycle by taking advantage of the internal degrees of freedom of an ideal gas [M. O. Scully, “The Quantum Afterburner”, Phys. Rev.
