Metal-insulator transition in superlattices
Shuai Dong, Rong Yu, Seiji Yunoki +3
The modulation of charge density and spin order in (LaMnO)/(SrMnO) (=1-4) superlattices is studied via Monte Carlo simulations of the double-exchange model. G…
Origin of the multiferroic spiral spin-order in the RMnO3 perovskites
Shuai Dong, Rong Yu, Seiji Yunoki +2
The origin of the spiral spin-order in perovskite multiferroic manganites MnO ( Tb or Dy) is here investigated using a two -orbitals double-exchange model.…
Ferromagnetic tendency at the surface of CE charge-ordered manganites
Shuai Dong, Rong Yu, Seiji Yunoki +2
Most previous investigations have shown that the surface of a ferromagnetic material may have antiferromagnetic tendencies. However, experimentally the opposite effect has been rec…
Large Magnetoresistance in a Manganite Spin-Tunnel-Junction Using LaMnO3 as Insulating Barrier
S. Yunoki, E. Dagotto, S. Costamagna +1
A spin-tunnel-junction based on manganites, with LaSrMnO (LSMO) as ferromagnetic metallic electrodes and the undoped parent compound LaMnO (LMO) as insulating b…
Unconventional metal-insulator transition in two dimensions
Manuela Capello, Federico Becca, Seiji Yunoki +1
We show, by using a correlated Jastrow wave function and a mapping onto a classical model, that the two-dimensional Mott transition in a simple half-filled one-band model can be un…
From Luttinger liquid to Mott insulator: the correct low-energy description of the one-dimensional Hubbard model by an unbiased variational approach
Manuela Capello, Federico Becca, Seiji Yunoki +2
We show that a particular class of variational wave functions reproduces the low-energy properties of the Hubbard model in one dimension. Our approach generalizes to finite on-site…
