May 4, 2022 Researchers use silicon nanoparticles to help visualize the coalescence of quantized vortices that occur in superfluid helium, which can help improve our understanding of quantum fluids and ...
Jan. 20, 2022 Researchers used optical trapping for the first time inside an ultracold superfluid made of helium. They were able to trap and monitor nanoparticles optically at ultralow temperatures. This technique ...
May 12, 2022 Researchers confirmed silicon nanoparticles are attracted to vortices in superfluid helium. Their simulations allowed them to visualize the process of vortex line recombination. The work may lead to ...
July 6, 2022 Physicists have created the first one-dimensional helium-based model system to advance research with applications to creating smaller ...
Mar. 1, 2023 Helium -- essential for many medical and industrial processes -- is in critically short supply worldwide. Production is also associated with significant carbon emissions, contributing to climate ...
May 9, 2022 Scientists used an unprecedented technique to detect that levels of helium are rising in the atmosphere, resolving an issue that has lingered among atmospheric chemists for ...
Mar. 29, 2021 While bionic devices are very safe, there has been no standard test for moisture leakage into the devices - until now. Researchers say a standard test will be increasingly important as bionic ...
Aug. 6, 2021 In a new study published in EPJ D, researchers have clearly identified particular areas where discrepancies arise between theoretical and experimental measurements of helium ionization by an ...
June 2, 2022 Scientists have created a 'time-crystal' a two-body system in an experiment that seems to bend the laws of physics. A 'two-level system' is a basic building block of a quantum ...
July 13, 2021 The absorption of energy from laser light by free electrons in a liquid has been demonstrated for the first time. Until now, this process was observed only in the gas phase. The findings open new ...
