MBL-mobile: Quantum engine based on many-body localization

Understand

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 many-body system.
• The system is ramped between a strongly localized MBL regime and a thermal (or weakly localized) regime.
