Exotic charge-density waves and superconductivity on the kagome lattice.

ABSTRACT: Loop current order has long been pursued in various electronic systems, including cuprates and honeycomb lattice materials, but its realization remains elusive in both experiment and theory. Intriguingly, recent experimental evidence for AV[Formula: see text]Sb[Formula: see text] (A = K, Rb, Cs) and related kagome metals hints at the formation of orbital currents in the charge-density wave-ordered regime, providing a mechanism for spontaneous time-reversal symmetry breaking in the absence of local moments. However, concrete theoretical model realizations of the loop-current order in the kagome lattice have been very challenging and remain an outstanding, unresolved problem. In this work, we comprehensively explore the competitive charge instabilities of the spinless kagome lattice with int
