CsV3Sb5 exhibits several emergent phenomena, including superconductivity (TC ~ 3.2 K), charge-density wave (TCDW ~ 98 K), and nematicity (Tnem ~ 36 K). Despite tremendous investigations for several years, the nature of the superconductivity and multiple electronic orders, as well as the relationship among them, remain elusive. In this study, we have investigated nematic susceptibility and...
Unconventional superconductivity often emerges in complex materials in which competing orders and complicated band structure obscure its origin. In contrast, $\kappa$-organics are geometrically frustrated quasi-2D single-band systems in which superconductivity arises near the bandwidth-tuned Mott metal-insulator transition in the absence of other orders. We show that in chemically substituted...
