Bipolaron in the t-J model coupled to longitudinal and transverse quantum lattice vibrations
Lev Vidmar, Janez Bonca, Sadamichi Maekawa +1
We explore the influence of two different polarizations of quantum oxygen vibrations on the spacial symmetry of the bound magnetic bipolaron in the context of the t-J model by usin…
Optical conductivity in the t-J-Holstein Model
L. Vidmar, J. Bonca, S. Maekawa
Using recently developed numerical method we compute charge stiffness and optical conductivity of the t-J model coupled to optical phonons. Coherent hole motion is most strongly in…
Coexistence of superconductivity and antiferromagnetism in self-doped bilayer t-t'-J model
J. Y. Gan, M. Mori, T. K. Lee +1
A self-doped bilayer t-t'-J model of an electron- and a hole-doped planes is studied by the slave-boson mean-field theory. A hopping integral between the differently doped planes,…
Numerical approach to low-doping regime of the t-J model
J. Bonca, S. Maekawa, T. Tohyama
We develop an efficient numerical method for the description of a single-hole motion in the antiferromagnetic background. The method is free of finite-size effects and allows calcu…
Dynamical mean field theory of optical third harmonic generation
S. A. Jafari, T. Tohyama, S. Maekawa
We formulate the third harmonic generation (THG) within the dynamical mean field theory (DMFT) approximation of the Hubbard model. In the limit of large dimensions, where DMFT beco…
Anomalous temperature dependence of the single-particle spectrum in the organic conductor TTF-TCNQ
N. Bulut, H. Matsueda, T. Tohyama +1
The angle-resolved photoemission spectrum of the organic conductor TTF-TCNQ exhibits an unusual transfer of spectral weight over a wide energy range for temperatures 60K<T<260K. In…
