## Charge-spin-orbital fluctuations in mixed valence spinels: Comparative study of ${\mathrm{AlV}}_{2}{\mathrm{O}}_{4}$ and ${\mathrm{LiV}}_{2}{\mathrm{O}}_{4}$

### In: Physical Review B, 2015, vol. 92, no. 19, p. 195150

Mixed valence spinels provide a fertile playground for the interplay between charge, spin, and orbital degrees of freedom in strongly correlated electrons on a geometrically frustrated lattice. Among them, AlV2O4 and LiV2O4 exhibit contrasting and puzzling behavior: self-organization of seven-site clusters and heavy fermion behavior. We theoretically perform a comparative study of... More
