Strange metals exhibit universal linear-in-temperature resistivity described by a Planckian
scattering rate, the origin of which remains elusive. By employing an approach inspired by …

The interpretation of how superconductivity disappears in cuprates at large hole doping has
been controversial. To address this issue, we present an experimental study of single-crystal …

Abstract The Mott-Ioffe-Regel limit sets the lower bound of carrier mean free path for
coherent quasiparticle transport. Metallicity beyond this limit is of great interest because it is …

Controlled engineering of vortex pinning sites in copper-oxide superconductors is a critical
issue in manufacturing devices based on magnetic flux quanta. To address this, we …
