Effect of frustration on charge dynamics for a doped two-dimensional triangular Hubbard lattice: Comparison with a square lattice

T. Tohyama

We examine the optical conductivity σ(ω) and the chemical potential μ, together with the spin correlation, in the strong-coupling limit of a hole-doped two-dimensional triangular H…

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…
