Heuristic bounds on superconductivity and how to exceed them

HIGHLIGHTS

• who: Johannes S. Hofmann from the Published in partnership with Nanjing University have published the paper: Heuristic bounds on superconductivity and how to exceed them, in the Journal: (JOURNAL) of 31/07/2022
• what: The authors examine three proposed bounds on Tc that are expressed as a fraction of a measurable physical quantity of a given system: an appropriately defined Fermi temperature, a characteristic phonon frequency, or the zero-temperature superfluid phase stiffness. While these putative bounds are physically motivated, and provide valuable intuition in many cases of practical importance, the authors show by explicit . . .
