Two-dimensional charge order in layered 2-1-4 perovskite oxides
Shigeki Onoda, Yukitoshi Motome, Naoto Nagaosa
Monte Carlo simulations are performed on the three-dimensional (3D) Ising model with the 2-1-4 layered perovskite structure as a minimal model for checkerboard charge ordering phen…

One-Dimensional Confinement and Enhanced Jahn-Teller Instability in LaVO
Yukitoshi Motome, Hitoshi Seo, Zhong Fang +1
Ordering and quantum fluctuations of orbital degrees of freedom are studied theoretically for LaVO in spin-C-type antiferromagnetic state. The effective Hamiltonian for the orb…
