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…
Fermi Arcs in the Superconducting Clustered State for Underdoped Cuprates
G. Alvarez, E. Dagotto
The one-particle spectral function of a state formed by superconducting (SC) clusters is studied via Monte Carlo techniques. The clusters have similar SC amplitudes but randomly di…
Ground-state reference systems for expanding correlated fermions in one dimension
F. Heidrich-Meisner, M. Rigol, A. Muramatsu +2
We study the sudden expansion of strongly correlated fermions in a one-dimensional lattice, utilizing the time-dependent density-matrix renormalization group method. Our focus is o…
