Abstract: We propose a quantum heat engine based on the ultrafast dynamical control of the magnetic properties of a nanoscale working body. The working principle relies on nonlinear phononics, an example for dynamical materials design. We… read more here.

Abstract: Many-body-localized (MBL) systems do not thermalize under their intrinsic dynamics. The athermality of MBL, we propose, can be harnessed for thermodynamic tasks. We illustrate this ability by formulating an Otto engine cycle for a quantum… read more here.

Abstract: We study a quantum Stirling cycle which extracts work using quantized energy levels of a potential well. The work and the efficiency of the engine depend on the length of the potential well, and the… read more here.

DOI: 10.1103/physreve.106.024105
Abstract: The Curzon-Ahlborn (CA) efficiency, as the efficiency at the maximum power (EMP) of the endoreversible Carnot engine, has significant impact on finite-time thermodynamics. However, the CA engine is based on many assumptions. In the past… read more here.
