Theory of Manganite Superlattice
Chungwei Lin, Andrew. J. Millis
A theoretical model is proposed for the (0,0,1) superlattice manganite system (LaMnO)(SrMnO). The model includes the electron-electron, electron-phonon, and coopera…
Theoretical Description of Pseudocubic Manganites
Chungwei Lin, Andrew. J. Millis
A comprehensive theoretical model for the bulk manganite system La(Ca,Sr)MnO is presented. The model includes local and cooperative Jahn-Teller distortions and the…
LaMnO is a Mott Insulator: an precise definition and an evaluation of the local interaction strength
Chungwei Lin, Andrew. J. Millis
We compare the interaction parameters measured on LaMnO to single site dynamical mean field estimates of the critical correlation strength needed to drive a Mott transition, fi…
Structural distortions and model Hamiltonian parameters: from LSDA to a tight-binding description of LaMnO_3
Claude Ederer, Chungwei Lin, Andrew J. Millis
The physics of manganites is often described within an effective two-band tight-binding (TB) model for the Mn e_g electrons, which apart from the kinetic energy includes also a loc…
Dynamical Mean Field Study of Model Double-Exchange Superlattices
Chungwei Lin, Satoshi Okamoto, Andrew J. Millis
A theoretical study of [001] "double exchange" superlattices is presented. The superlattice is defined in terms of an O perovskite crystal. Itinerant electrons hop among th…
Implications of the Low-Temperature Instability of Dynamical Mean Theory for Double Exchange Systems
chungwei Lin, Andrew. J. Millis
The single-site dynamical mean field theory approximation to the double exchange model is found to exhibit a previously unnoticed instability, in which a well-defined ground state…
