Strong Correlation Between ELF Networking and Conventional Superconductivity for Hydrogen Based Compounds
ORAL
Abstract
The more recent discoveries in the field of Hydrogen based BCS superconductivity show that Tc can span from few Kelvins as for AlH3 and PrH9 with respective Tcs being 4K and 7K to much higher values as in the case for H3S, YH9 and LaH10 with respective Tcs of with 203K, 243K and 260K. In addition the latest finding for a Sulful-Carbon-Hydrogen based compound [1] with Tc above 280 K proves the possibility of room-temperature superconductivity. The greatest challenge is now to achieve ambient temperature-pressure superconductivity.
Moreover there are more then hundred predicted compounds [2,3] and there is the possibility to classify systems based on their properties in order to obtain prediction trends. Although the possibility to rely on simple impactful variables for predictions is still missing.
In this talk we investigate the chemical, structural and electronic properties for a wide set of Hydrogen based superconductors. We then propose a simple general observable based on the study of the ELF showing an incredible strong correlation with the Tc.
