Non-magnetic insulating phase induced by Jahn-Teller effect in RNiO${}_3$

Sangeeta Rajpurohit, Liang Z. Tan, Tadashi Ogitsu +1

We propose a three-dimensional multi-orbital tight-binding model for rare-earth nickelates RNiO${}_3$ that treats charge, spin, orbital, and lattice degrees of freedom on equal footi…
