For an understanding of a heat engine working in the microscopic scale, it is often necessary to estimate the amount of reversible work extracted by isothermal expansion of the quantum gas used as its working substance. We consider an engine with a movable wall, modeled as an infinite square well with a delta peak inside. By solving the resulting one-dimensional Schr¨odinger equation, we obtain the energy levels and the thermodynamic potentials. Our result shows how quantum tunneling degrades…

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
Quantum Maxwell's demon in thermodynamic cycles.
It is discovered that a MD with quantum coherence or one at a temperature lower than the molecule's heat bath can enhance the ability of the whole working substance, formed by the heat engine plus the MD, to do work outside.

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
On the concept of pressure in quantum mechanics
Heat and work are fundamental concepts for thermodynamical systems. When these are scaled down to the quantum level they require appropriate embeddings. Here we show that the dependence of the
Quantum Szilard engine.
The first complete quantum analysis of the Szilard engine is presented, and an analytic expression of the quantum-mechanical work performed by a quantum SZE containing an arbitrary number of molecules is derived.
Szilard’s information heat engines in the deep quantum regime
We investigate Szilard’s information heat engine in the deep quantum regime. If the ground state is non-degenerate, the work extracted from the engine divided by temperature, ~S, vanishes as the
Revivals in an infinite square well in the presence of a δ well
We have investigated quantum revivals of wave packets in a one-dimensional infinite square well potential containing a δ well in the middle. The time-dependent Schrodinger equation for this composite
Unusual quantum states: non–locality, entropy, Maxwell's demon and fractals
This paper analyses the mathematical properties of some unusual quantum states that are constructed by inserting an impenetrable barrier into a chamber confining a single particle. If the barrier is

Abstract By considering level shifting during the insertion process we revisit the quantum Szilard engine (QSZE) with fully quantum consideration. We derive the general expressions of the heat
Exact solutions of a particle in a box with a delta function potential: The factorization method
We use the factorization method to find the exact eigenvalues and eigenfunctions for a particle in a box with the delta function potential V(x)=λδ(x−x0). We show that the presence of the potential
