Abstract: A quantum Otto engine based on a three-dimensional harmonic oscillator is proposed. One of the modes of this oscillator functions as the working fluid, while the other two play the role of baths. The coupling between the working fluid and the baths is controlled using an external central potential. All four strokes of the engine are simulated numerically, exploring the nonadiabatic effects in the compression and expansion phases, as well as the energy transfer during the working fluid's contact with the baths. The efficiency and power of several realizations of the proposed engine are also computed with the former agreeing well with the theoretical predictions for the quantum Otto cycle.

Advantages of non-Hookean coupling in a measurement-fueled two-oscillator engine [65.268245109828]
A quantum engine composed of two oscillators with a non-Hookean coupling is proposed. Unlike the more common quantum heat engines, the setup introduced here does not require heat baths as the energy for the operation originates from measurements. Numerical simulations are used to demonstrate the measurement-driven fueling, as well as the reduced decoupling energy.

Pulsed multireservoir engineering for a trapped ion with applications to state synthesis and quantum Otto cycles [68.8204255655161]
Reservoir engineering is a remarkable task that takes dissipation and decoherence as tools rather than impediments. We develop a collisional model to implement reservoir engineering for the one-dimensional harmonic motion of a trapped ion. Having multiple internal levels, we show that multiple reservoirs can be engineered, allowing for more efficient synthesis of well-known non-classical states of motion.

Driven quantum harmonic oscillators: A working medium for thermal machines [0.0]
We consider a working substance that is permanently coupled to two or more baths at different temperatures and continuously driven. We derive the heat flows and power of the working device which can operate as an engine, refrigerator or accelerator. An increased driving frequency can lead to a change of functioning to a dissipator.
