HIGHLIGHTED ARTICLES

FEATURED IN PHYSICS

EDITORS' SUGGESTION

Observation of the Mass Difference between Neutral Charm-Meson Eigenstates

R. Aaij et al. (LHCb Collaboration)

Phys. Rev. Lett. 127, 111801 (2021) - Published 7 September, 2021

The observation of neutral D mesons oscillating into their antiparticle partners provides constraints on new heavy particles that can’t be directly produced by high-energy colliders.

EDITORS' SUGGESTION

Suppressing the Kibble-Zurek Mechanism by a Symmetry-Violating Bias

J. Rysti, J. T. Mäkinen, S. Autti, T. Kamppinen, G. E. Volovik, and V. B. Eltsov

Phys. Rev. Lett. 127, 115702 (2021) - Published 8 September, 2021

Researchers demonstrate that they can suppress the formation of defects that appear in superfluid helium-3 when it undergoes a continuous phase transition, allowing them to influence the form of the system’s final phase.

Anomalous Diffusion and Lévy Walks Distinguish Active from Inertial Turbulence

Siddhartha Mukherjee, Rahul K. Singh, Martin James, and Samriddhi Sankar Ray

Phys. Rev. Lett. 127, 118001 (2021) - Published 9 September, 2021

Simulations show that the harder bacteria in a swarm push against one another, the more likely they are to go on long “walks.”

EDITORS' SUGGESTION

Defect Saturation in a Rapidly Quenched Bose Gas

Junhong Goo, Younghoon Lim, and Y. Shin

Phys. Rev. Lett. 127, 115701 (2021) - Published 8 September, 2021

Deviations in the defect saturation in a weakly interacting Bose gas suggest that the effect goes beyond the description provided by the Kibble–Zurek mechanism.
