The optimal power performance of a first-principle quantum heat engine model shows friction-like phenomena when the internal fluid Hamiltonian does not commute with the external control field. The model is based on interacting two-level systems where the external magnetic field serves as a control variable.

The irreversible nature of the engine is the result of finite heat transfer rates and frictionlike behavior due to noncommutability of the internal and external Hamiltonians. Expand
Quantum Otto cycle with inner friction: finite-time and disorder effects
The concept of inner friction, by which a quantum heat engine is unable to follow adiabatically its strokes and thus dissipates useful energy, is illustrated in an exact physical model where theExpand
Work production of quantum rotor engines
We study the mechanical performance of quantum rotor heat engines in terms of common notions of work. Our investigation focuses on quantum models of a mill driven by the directed heat flow from a hotExpand
Friction due to inhomogeneous driving of coupled spins in a quantum heat engine
We consider two spin-1/2 particles with isotropic Heisenberg interaction, as the working substance of a quantum heat engine. We observe a frictional effect on the adiabatic branches of the heatExpand
Irreversible performance of a quantum harmonic heat engine
The unavoidable irreversible loss of power in a heat engine is found to be of quantum origin. Following thermodynamic tradition, a model quantum heat engine operating in an Otto cycle is analysed,Expand
Quantum limit to nonequilibrium heat-engine performance imposed by strong system-reservoir coupling.
We show that finite system-reservoir coupling imposes a distinct quantum limit on the performance of a nonequilibrium quantum heat engine. Even in the absence of quantum friction along the isentropicExpand
Friction-free quantum machines
The operation of a quantum heat engine in finite time generally faces a trade-off between efficiency and power. Using shortcuts to adiabaticity (STA), this trade off can be avoided to engineerExpand
Thermodynamic Geometry of Microscopic Heat Engines.
Focusing on Lindblad dynamics, a second bound is derived showing that coherence as a genuine quantum effect inevitably reduces the performance of slow engine cycles regardless of the driving amplitudes. Expand
Experimental Demonstration of Quantum Effects in the Operation of Microscopic Heat Engines.
Here, an ensemble of nitrogen vacancy centers in diamond is used for implementing two types of quantum heat engines, and the presence of such internal coherence causes different types of Quantum heat engines to become thermodynamically equivalent. Expand
Performance of a quantum heat engine cycle working with harmonic oscillator systems
A cycle model of an irreversible heat engine working with harmonic systems is established in this paper. Based on the equation of motion of an operator in the Heisenberg picture and semi-groupExpand
