Effect of nonmagnetic impurities on stripes in high-Tc cuprates
T. Tohyama, M. Takahashi, S. Maekawa
We perform the numerically exact diagonalization study of the t-J model with nonmagnetic impurities to clarify the relation between Zn impurities and the stripes. By examining the…

Nonlinear optical response and spin-charge separation in one-dimensional Mott insulators
Y. Mizuno, K. Tsutsui, T. Tohyama +1
We theoretically study the nonlinear optical response and photoexcited states of the Mott insulators. The nonlinear optical susceptibility χ^(3) is calculated by using the exact di…
