Low Temperature Magnetic Properties of the Double Exchange Model
Jun Zang, H. Röder, A. R. Bishop +1
We study the {\it ferromagnetic} (FM) Kondo lattice model in the strong coupling limit (double exchange (DE) model). The DE mechanism proposed by Zener to explain ferromagnetism ha…
Double Degeneracy and Jahn-Teller Effects in CMR Perovskites
Jun Zang, A. R. Bishop, H. Roder
Jahn-Teller (JT) electron-phonon coupling effects in the colossal magnetoresistance perovskite compounds are investigated. Electron-electron correlations between…
Frustrated Spin-Peierls Chains
Jun Zang, A. R. Bishop, D. Schmeltzer
We study the phase diagram, ground state properties, and excitation gaps of a frustrated spin-Peierls chain, i.e. a spin-Peierls chain with both nearest neighbor exchange and…
Structure of the Magneto-Exciton and Optical Properties in Fractional Quantum Hall Systems
Jun Zang, Joseph L Birman
We report calculated dependence of magneto-exciton energy spectrum upon electron-hole separation in Fractional Quantum Hall systems. We calculated the dependence of photolumine…
Theory of Second Order Optical Processes from A Luttinger Liquid
Jun Zang, Joseph L Birman, Zhao-Bin Su
We develop a theory for the total optical secondary emission from a 1D interacting electron system modelled as a Tomonaga-Luttinger liquid. We separate the emission into two parts…
