## Quantum engine based on many-body localization

By Nicole Yunger Halpern, Christopher David White, Sarang Gopalakrishnan, and Gil Refael from Recent Articles in Phys. Rev. B. Published on Jan 22, 2019.

Author(s): Nicole Yunger Halpern, Christopher David White, Sarang Gopalakrishnan, and Gil Refael

Many-body localization (MBL) is a phase of quantum matter that has attracted much experimental and theoretical attention recently. MBL particles stay fixed for long times, resisting thermalization. This athermality, the authors show, can serve as a resource in thermodynamic tasks. They formulate an engine cycle for a quantum many-body system tuned between MBL and thermal phases. MBL enables the engine to scale robustly, from mesoscale to macroscale, and improves the engine’s reliability. This work opens the door to technological applications of MBL.

## Spin-dependent electron transmission model for chiral molecules in mesoscopic devices

By Xu Yang, Caspar H. van der Wal, and Bart J. van Wees from Recent Articles in Phys. Rev. B. Published on Jan 18, 2019.

Author(s): Xu Yang, Caspar H. van der Wal, and Bart J. van Wees

Experimental observations have suggested that certain chiral molecules may be able to function as spin polarizers, an effect that promises new spintronic applications but whose mechanism remains unclear. Here, the authors bypass the microscopic origin of the effect and approach it by applying universal theorems of electrical conduction to mesoscopic devices that contain chiral molecules. This leads to a theoretical model that can quantitatively evaluate transport experiments and distinguish spin signals related to chiral molecules from other magnetic field dependent signals.

The high-pressure dc susceptibility has been measured in order to explore the pressure dependence on the dimensionality of the magnetic interaction network in IBPSSEt, which displays an ideal three-dimensional ferromagnetic network at 2 GPa with ${T}_{C}$ = 27.5 K. At more elevated pressures, the structure is best described in terms of a one-dimensional ferromagnetic chain. [Phys. Rev.
