FEATURED IN PHYSICS

Material Size Dependence on Fundamental Constants

Lukáš F. Pašteka, Yongliang Hao, Anastasia Borschevsky, Victor V. Flambaum, and Peter Schwerdtfeger

Phys. Rev. Lett. 122, 160801 (2019) - Published 24 April, 2019

Searching for variations in fundamental constants—which are predicted by some theories of dark matter—might potentially be done by monitoring the sizes of solid crystals.

Layering Transition in Superfluid Helium Adsorbed on a Carbon Nanotube Mechanical Resonator

Phys. Rev. Lett. 122, 165301 (2019) - Published 23 April, 2019

Experiments show that a superfluid helium film forming on a carbon nanotube grows layer by layer, with one layer fully forming before the next one starts.

Phys. Rev. Lett. 122, 163601 (2019) - Published 22 April, 2019

The first experimental observation of atom number fluctuations in atomic Bose-Einstein condensates demonstrates that the preparation of ultracold gases has reached a point where the fundamental fluctuations of the system have to be considered in precision experiments.

Mats Barkman, Albert Samoilenka, and Egor Babaev

Phys. Rev. Lett. 122, 165302 (2019) - Published 25 April, 2019
