Fermi-liquid transport beyond the upper critical field in superconducting La${}_2$PrNi${}_2$O${}_7$ thin films

Yu-Te Hsu, Yidi Liu, Yoshimitsu Kohama +7

Unconventional superconductivity typically emerges out of a strongly correlated normal state, manifesting as a highly renormalized Fermi liquid or a strange metal with $T$-linear r…
