Tunneling Electroresistance in Ferroelectric Tunnel Junctions with a Composite Barrier
M. Ye. Zhuravlev, Y. Wang, S. Maekawa +1
Tunneling electroresistance (TER) effect is the change in the electrical resistance of a ferroelectric tunnel junction (FTJ) associated with polarization reversal in the ferroelect…
Spin Dependent Transport in Magnetic Nanostructures
S. Maekawa
Recent progress in physics on spin dependent transport in magnetic nanostructures is reviewed. Special attention is paid on the spin accumulation and spin current caused by spin in…
Heavy Quasiparticles in the Anderson Lattice Model
K. Tsutsui, Y. Ohta, R. Eder +3
An exact-diagonalization technique on small clusters is used to study the dynamics of the one-dimensional symmetric Anderson lattice model. Our calculated excitation spectra reprod…
Excitation Spectra of the Negative-U Hubbard Model: A Small-Cluster Study
Y. Ohta, A. Nakauchi, R. Eder +2
An exact-diagonalization technique on small clusters is used to study low-lying excitations and superconductivity in the two-dimensional negative- Hubbard model. We first calcul…
Ground state properties and dynamics of the bilayer t-J model
R. Eder, Y. Ohta, S. Maekawa
We present an exact diagonalization study of bilayer clusters of t-J model. Our results indicate a crossover between two markedly different regimes which occurs when the ratio J_pe…
Anomalous Spin and Charge Dynamics of the 2D t-J Model at low doping
R. Eder, Y. Ohta, S. Maekawa
We present an exact diagonalization study of the dynamical spin and density correlation function of the 2D t-J model for hole doping < 25%. Both correlation functions show a remark…
