HIGHLIGHTED ARTICLES

FEATURED IN PHYSICS

EDITORS' SUGGESTION

Identification of a Gravitational Arrow of Time

Julian Barbour, Tim Koslowski, and Flavio Mercati

Phys. Rev. Lett. 113, 181101 (2014) - Published 29 October, 2014

Masses evolving under Newtonian gravity have a preferred direction of time without special initial conditions.

FEATURED IN PHYSICS

Single Molecular Spectroscopy: Identification of Individual Fullerene Molecules

Luiz H. G. Tizei, Zheng Liu, Masanori Koshino, Yoko Iizumi, Toshiya Okazaki, and Kazu Suenaga

Phys. Rev. Lett. 113, 185502 (2014) - Published 29 October, 2014

The energy lost by electrons passing through a material can reveal the symmetry of individual molecules inside the sample.

EDITORS' SUGGESTION

Indications of a Late-Time Interaction in the Dark Sector

Valentina Salvatelli, Najla Said, Marco Bruni, Alessandro Melchiorri, and David Wands

Phys. Rev. Lett. 113, 181301 (2014) - Published 30 October, 2014

Discrepancies between different cosmological datasets could indicate interactions between dark matter and dark energy that occurred late in cosmological evolution, when the universe was approximately 6 billion years old.

EDITORS' SUGGESTION

Lorentz Invariance in Chiral Kinetic Theory

Jing-Yuan Chen, Dam T. Son, Mikhail A. Stephanov, Ho-Ung Yee, and Yi Yin

Phys. Rev. Lett. 113, 182302 (2014) - Published 30 October, 2014

A kinetic theory, with explicit Lorentz invariance, is derived for chiral fermions in an external electromagnetic field. This theory provides the correct form for the chiral vortical effect — the appearance of a current in a system undergoing rotation.

EDITORS' SUGGESTION

Local to Extended Transitions of Resonant Defect Modes

Joseph Lydon, Marc Serra-Garcia, and Chiara Daraio

Phys. Rev. Lett. 113, 185503 (2014) - Published 29 October, 2014

A linear chain of beads exhibits localized vibrational states when a defect is introduced into the chain. If the defect is resonant, the length of chain involved in this localized excitation can be tuned.

EDITORS' SUGGESTION

Frequency Comb Generation in Superconducting Resonators

R. P. Erickson, M. R. Vissers, M. Sandberg, S. R. Jefferts, and D. P. Pappas

Phys. Rev. Lett. 113, 187002 (2014) - Published 30 October, 2014

Superconducting niobium-titanium nitride resonators are used to generate multi-octave frequency combs in the microwave regime.

EDITORS' SUGGESTION

Two-Dimensional Analysis of the Double-Resonant 2D Raman Mode in Bilayer Graphene

Felix Herziger, Matteo Calandra, Paola Gava, Patrick May, Michele Lazzeri, Francesco Mauri, and Janina Maultzsch

Phys. Rev. Lett. 113, 187401 (2014) - Published 30 October, 2014

Raman spectroscopy, in particular the 2D Raman mode, is widely used to characterize bilayer graphene. The assumption that the 2D mode can be interpreted in terms of four independent scattering processes is shown to be incorrect.

EDITORS' SUGGESTION

Terasaki Spiral Ramps in the Rough Endoplasmic Reticulum

Jemal Guven, Greg Huber, and Dulce María Valencia

Phys. Rev. Lett. 113, 188101 (2014) - Published 28 October, 2014

A model for the fundamental building blocks of fluid membranes addresses how chiral stacking occurs in the endoplasmic reticulum, an essential cellular organelle.
