Abstract: We investigate the higher-order topological insulators on the breathing kagome lattices with $p$-orbital freedom. The bulk topological phase diagram is obtained by calculating the ${Z}_{3}$ Berry phase of the $p$-band model. The existence of a… read more here.

Abstract: Motivated by recent experiments on the vanadium oxyfluoride material DQVOF, we examine possible spin liquid phases on a breathing kagome lattice of S=1/2 spins. By performing a projective symmetry group analysis, we determine the possible… read more here.

DOI: 10.1103/physrevb.99.165141
Abstract: We theoretically study the topological properties of the tight-binding model on the breathing kagome lattice with antisymmetric spin-orbit coupling (SOC) between nearest neighbors. We show that the system hosts nontrivial topological phases even without second-nearest-neighbor… read more here.

DOI: 10.1103/physrevlett.120.227201
Abstract: We present measurements on a series of materials, Li_{2}In_{1-x}Sc_{x}Mo_{3}O_{8}, that can be described as a 1/6th-filled breathing kagome lattice. Substituting Sc for In generates chemical pressure which alters the breathing parameter nonmonotonically. Muon spin rotation… read more here.
