Stripe Phases in Layered Nickelates

Strongly Correlated Electrons 2022-01-25 v1 Materials Science

Abstract

To describe quasi two-dimensional nickelates we introduce an effective Hamiltonian for ege_g electrons which includes the kinetic energy, on-site Coulomb interactions, spin-spin and Jahn-Teller (static) terms. The experimental stripe phases are correctly reproduced by the model. The mechanisms responsible for stripe formation are different than those reported in cuprates and manganites.
