A model is proposed for an adaptive heat engine that modifies its internal structure in order to remain operative when the external conditions (like the temperatures of the thermal baths) change.

Experiments using high-energy-density laboratory plasmas at conditions comparable to astrophysical systems show that the T+ $^{3}$ He fusion reaction is not responsible for the high levels of $^{6}$ Li observed in primordial material.

EDITORS' SUGGESTION

Emergence of a Metallic Quantum Solid Phase in a Rydberg-Dressed Fermi Gas

Phys. Rev. Lett. 117, 035301 (2016) - Published 14 July, 2016

A metallic state resulting from a charge-density wave instability is theoretically predicted for a Fermi gas of Rydberg atoms with repulsive pair interactions.

Density and Phase State of a Confined Nonpolar Fluid

Daniel F. Kienle and Tonya L. Kuhl

Phys. Rev. Lett. 117, 036101 (2016) - Published 14 July, 2016

Does it freeze or go glassy? Experiments show that a nonpolar fluid undergoes a glass transition, rather than a freezing transition, when it is confined in very thin channels.

EDITORS' SUGGESTION

Omnidirectional Measurements of Angle-Resolved Heat Capacity for Complete Detection of Superconducting Gap Structure in the Heavy-Fermion Antiferromagnet ${UPd}_{2} {Al}_{3}$

Phys. Rev. Lett. 117, 037001 (2016) - Published 12 July, 2016

The measured heavy electron density of states in the correlated (unconventional) superconductor UPd $_{2}$ Al $_{3}$ contains horizontal line nodes in the gap symmetry, a signal that the superconducting pairing mechanism could be mediated by magnetic fluctuations.

EDITORS' SUGGESTION

All-in–all-Out Magnetic Order and Propagating Spin Waves in ${Sm}_{2} {Ir}_{2} O_{7}$

C. Donnerer, M. C. Rahn, M. Moretti Sala, J. G. Vale, D. Pincini, J. Strempfer, M. Krisch, D. Prabhakaran, A. T. Boothroyd, and D. F. McMorrow

Phys. Rev. Lett. 117, 037201 (2016) - Published 11 July, 2016

Resonant x-ray scattering experiments show that a pyrochlore iridate exhibits all-in all-out ordering—the moments either all point towards the center of the crystal unit cell, or away from it—which is a prerequisite for stabilizing a Weyl semimetal phase. This suggests that some pyrochlore iridates may behave as Weyl semimetals.

EDITORS' SUGGESTION
