Scientists from Skoltech, the Shubnikov Institute of Crystallography, and the Center for High Pressure Science and Technology Advanced Research (HPSTAR) in Beijing, China, are exploring the superconductivity of polyhydrides—compounds of metals and hydrogen formed at high pressure. These compounds are expected to function at higher temperatures than cuprate superconductors.
superconductivity started to gain interest. In this context, it is important to understand and analyze physical mechanisms of conductivity and superconductivity in hydrides, as well as the structure of new materials, otherwise we can obtain inaccurate data. Our studies successfully address this issue," states study co-author, Assistant Professor from the Project Center for Energy Transition Alexander Kvashnin.
In the new paper, researchers studied the chemical interaction between tin and hydrogen under the pressure of 1.8–2.4 million atmospheres through electric transport measurements and synchrotron X-ray single crystal and powder diffraction. through the sample. We studied the structure of new tin hydrides using single crystal and powder X-ray diffraction," describes Semenok.under pressure exhibits unusual properties—electrical resistance and magnetoresistance of this hydride in the non-superconducting state are almost linearly dependent on the temperature and applied magnetic field accordingly. The upper critical magnetic field is also linearly dependent on the temperature down to 2 K deviating from the common models.

Researchers propose using pulsars to localize gravitational wave sourcesCurrent gravitational wave observatories have two significant limitations. The first is that they can only observe powerful gravitational bursts such as the mergers of black holes and neutron stars. The second is that they can only observe these mergers for wavelengths on the order of hundreds to thousands of kilometers. This means we can only observe stellar mass mergers. Of course, there's a lot of interesting gravitational astronomy going on at other wavelengths and noise levels, which has motivated astronomers to get clever. One of these clever ideas is to use pulsars as a telescope. Research has been published on the pre-print server arXiv.
