Light Higgs channel of the resonant decay of magnon condensate in superfluid 3He-B

open access: yesNature Communications, 2016
The order parameter describing the spontaneous symmetry breaking which occurs when a system becomes a superfluid is analogous to the Higgs field in particle physics from which the Higgs boson arises. Here, the authors demonstrate the existence of a light

Low temperature opacities [PDF]

open access: yesInternational Astronomical Union Colloquium, 1994
AbstractThe importance of low temperature opacities in stellar calibrations led us to compute new sets of Rosseland mean opacities for different Z-values. For the solar metallicity, these tables have been compared to those of Alexander (1975), Cox (1983), Sharp (1991) and Kurucz (1992).

TAPSO at Low Temperature

open access: yesActa Crystallographica Section C Crystal Structure Communications, 1996
The crystal structure of TAPSO, 2-hydroxy-3-[tris-(hydroxymethyl)methylamino]propane-1-sulfonic acid, C7H17NO7S, was determined at 153 K. This widely used buffer crystallizes as a zwitterion, 2-hydroxy-3-[tris(hydroxymethyl)methylammonio]propane-l-sulfonate, and crystal cohesion is provided by a dense network of hydrogen bonds.

Matrix-Assisted Processes in CH4-Doped Ar Ices Irradiated with an Electron Beam

open access: yesMethane, 2023
The relaxation processes induced by exposure of the Ar matrices doped with CH4 (0.1–10%) to an electron beam were studied with a focus on the dynamics of radiolysis products—H atoms, H2 molecules, CH radicals, and energy transfer processes.

Evidence of a reduction in cloud condensation nuclei activity of water-soluble aerosols caused by biogenic emissions in a cool-temperate forest

open access: yesScientific Reports, 2017
Biogenic organic aerosols can affect cloud condensation nuclei (CCN) properties, and subsequently impact climate change. Large uncertainties exist in how the difference in the types of terrestrial biogenic sources and the abundance of organics relative ...

Weakened overturning and tide control the properties of Oyashio Intermediate Water, a key water mass in the North Pacific

open access: yesScientific Reports, 2021
The western subarctic Pacific exhibits major biological productivity fed by the Oyashio Current and its two source waters: Western Subarctic Water, which supplies nutrients from the subarctic Pacific, and cold Okhotsk Sea Intermediate Water (OSIW), which

Low-temperature magnetic properties of magnetite

open access: yes, 2000
Although several studies have recommended removal of secondary components of magnetic remanence by zero-field cycling from room temperature to a temperature much lower than the low temperature transition for magnetite (about 120 K), the method has not ...

Low-Temperature Magnetic Properties and Magnetocaloric Effect of Fe-Zr-Cu Amorphous Alloys

open access: yes, 2020
In this work, low-temperature magnetic properties and magnetocaloric properties of Fe91-xZr9Cux (x = 0.0, 0.4 and 1.0) amorphous ribbons were investigated.
