Constraining the Spin-Dependent WIMP-Nucleon Cross Sections with XENON1T

E. Aprile et al. (XENON Collaboration)

EDITORS' SUGGESTION

Four-Body Scale in Universal Few-Boson Systems

B. Bazak, J. Kirscher, S. König, M. Pavón Valderrama, N. Barnea, and U. van Kolck

Phys. Rev. Lett. 122, 143001 (2019) - Published 10 April, 2019

New numerical and analytical results highlight the need of a four-body force to accurately describe the interaction of four-body scale universal systems governed by large scattering lengths.

EDITORS' SUGGESTION

Superfluid Helium in Three-Dimensional Counterflow Differs Strongly from Classical Flows: Anisotropy on Small Scales

L. Biferale, D. Khomenko, V. L’vov, A. Pomyalov, I. Procaccia, and G. Sahoo

Phys. Rev. Lett. 122, 144501 (2019) - Published 8 April, 2019

Isotropy analysis shows that, while turbulence in classical fluids tends towards isotropy and homogeneity with decreasing scales, the opposite trend is true for superfluid helium flows.

EDITORS' SUGGESTION

Many-Body Chern Number without Integration

Koji Kudo, Haruki Watanabe, Toshikaze Kariyado, and Yasuhiro Hatsugai

Phys. Rev. Lett. 122, 146601 (2019) - Published 9 April, 2019

Numerical calculations show that an integration previously thought to be essential for obtaining the many-body Chern number is not necessary for large systems, which could significantly reduce the numerical cost in computing the many-body Chern number.
