Two coupled double quantum-dot systems as a working substance for heat machines.

- PhysicsPhysical review. E
- 2021

A conceptual design for quantum heat machines using a pair of coupled double quantum dots (DQDs), each DQD with an excess electron to interact, as an working substance, and defines a compression ratio as the ratio between the Coulomb couplings.

Single-Atom Heat Machines Enabled by Energy Quantization.

- PhysicsPhysical review letters
- 2018

It is shown that energy quantization alone may alter and increase machine performance in terms of output work, efficiency, and even operation mode, and that quantum thermodynamics enables the realization of classically inconceivable Otto machines, such as those with an incompressible working substance.

Magnetically-Driven Quantum Heat Engines: The Quasi-Static Limit of Their Efficiency

- PhysicsEntropy
- 2016

The general quantum thermodynamics formalism developed in order to analyze this type of QHEN is presented and applied to describe the theoretical efficiency of two different practical implementations of this concept: an array of semiconductor quantum dots and an ensemble of graphene flakes submitted to mechanical tension.

Transformation Electronics: Tailoring the Effective Mass of Electrons

- Physics
- 2012

The speed of integrated circuits is ultimately limited by the mobility of electrons or holes, which depend on the effective mass in a semiconductor. Here, building on an analogy with electromagnetic…

Quantum thermodynamic cycles and quantum heat engines.

- PhysicsPhysical review. E, Statistical, nonlinear, and soft matter physics
- 2007

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.

Efficiency of Harmonic Quantum Otto Engines at Maximal Power

- PhysicsEntropy
- 2018

This work analyzes two examples of endoreversible Otto engines within the same conceptual framework as Curzon and Ahlborn’s original treatment and finds that for endore reversible Otto cycles in classical harmonic oscillators the efficiency at maximal power is given by the Curzon–Ahlborn efficiency.
