Abstract: After being expected as a promising analogue to cuprates for decades, superconductivity was recently discovered in infinite-layer nickelates, providing new opportunities to explore mechanisms of high-temperature superconductivity. However, in sharp contrast to the single-band and anisotropic… read more here.

DOI: 10.1103/physrevb.103.l060506
Abstract: High critical temperature superconductivity often occurs in systems where an antiferromagnetic order is brought near $T=0$ K by slightly modifying pressure or doping. ${\mathrm{CaKFe}}_{4}{\mathrm{As}}_{4}$ is a superconducting, stoichiometric iron-pnictide compound showing optimal superconducting critical temperature… read more here.

DOI: 10.1126/sciadv.adf1414
Abstract: A two-dimensional, anisotropic superconductivity was recently found at the KTaO3(111) interfaces. The nature of the anisotropic superconducting transition remains a subject of debate. To investigate the origins of the observed behavior, we grew epitaxial KTaO3(111)-based… read more here.
