Nearly twofold overestimation of the superconducting volume fraction in pressurized Ruddlesden-Popper nickelates
Aleksandr V. Korolev, Evgeny F. Talantsev
The detection of the DC diamagnetic state in pressurized Ruddlesden-Popper nickelates remained an unsolved experimental problem until recent experiments in which Zhu et al. mea…
Best practices for a proper evaluation and conversion of physical property equations in superconductors: the examples of WHH formulation, Bean model and other cases of interest
Chiara Tarantini, Evgeny F. Talantsev, Ilaria Pallecchi +3
In recent years there have been growing concerns about the proper evaluation of physical properties of superconductors, in particular for quantities extracted from magnetic charact…
Long-Term Stability of Superconducting Metal Superhydrides
Vasily S. Minkov, Mikhail A. Kuzovnikov, Panpan Kong +11
Zhou et al., in their recent publication (Nat. Commun. 16, 1135, 2025), reported the synthesis of lanthanum superhydride, LaHx (x = 10.2-11.1), by laser heating LaH3 with NH3BH3 at…
The compliance of the molecular hydride superconductor with the Migdal's theorem
E. F. Talantsev, Yu. V. Blinova, A. V. Korolev
The discovery of near-room-temperature superconductivity in H3S sparked experimental and theoretical studies of highly compressed hydrides with the aim of obtaining room-temperatur…
Structural and superconducting parameters of highly compressed sulfur
Evgeny F. Talantsev, Evgeniya G. Valova-Zaharevskaya
Sulfur was the first nonmetal element which was transformed to a superconductor by applying megabar pressure. Recent pioneering experimental developments in measuring the supercond…
Fundamental nature of the self-field critical current in superconductors
Evgeny F. Talantsev, Jeffery L. Tallon
