Interlocked Vortex Order in the Frustrated $A_3$V$_9$Te$_{13}$ Lattice ($A$=Cs,Rb)
Recently synthesized $A_3$V$_9$Te$_{13}$ ($A$ = Cs, Rb) provides a unique platform for exploring the interplay between geometric frustration, magnetism, and correlated electronic states beyond conventional kagome systems. Based on first-principles calculations, we demonstrate that the frustrated V sublattice naturally...
