Search for a Dark Photon in $e^{+} e^{-}$ Collisions at BaBar

J. P. Lees et al. (BaBar Collaboration)

Phys. Rev. Lett. 113, 201801 (2014) - Published 10 November, 2014

EDITORS' SUGGESTION

Dynamic Control of the Polarization of Intense Laser Beams via Optical Wave Mixing in Plasmas

P. Michel, L. Divol, D. Turnbull, and J. D. Moody

Phys. Rev. Lett. 113, 205001 (2014) - Published 14 November, 2014

The polarization of an intense laser beam can theoretically be controlled by mixing it with a second beam in a plasma.

EDITORS' SUGGESTION

Anomalous Weak Values Are Proofs of Contextuality

Matthew F. Pusey

Phys. Rev. Lett. 113, 200401 (2014) - Published 12 November, 2014

Weak measurements whose results exceed the largest eigenvalue of an operator manifest nonclassical behavior called contextuality.

EDITORS' SUGGESTION

Peltier Cooling of Fermionic Quantum Gases

Ch. Grenier, A. Georges, and C. Kollath

Phys. Rev. Lett. 113, 200601 (2014) - Published 12 November, 2014

Simultaneous evaporative cooling of particles and holes would allow faster, deeper cooling of neutral Fermi gases. This new method could allow the gas to be cooled sufficiently for superfluidity and ultra-low temperature transport, amongst other things, to be studied in these systems.
