Conditions for orbital selective altermagnetism in Sr${}_2$RuO${}_4$: tight binding model, similarities with cuprates and implications on superconductivity

Carmine Autieri, Giuseppe Cuono, Debmalya Chakraborty +2

The vibrational modes in Sr${}_2$RuO${}_4$ easily induce octahedral rotations without tilting. Being on the verge of a magnetic instability, such propensity of octahedral rotation may…
