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…

Angle-resolved photoemission in high Tc cuprates from theoretical viewpoints

T. Tohyama, S. Maekawa

The angle-resolved photoemission (ARPES) technique has been developed rapidly over the last decay, accompanied by the improvement of energy and momentum resolutions. This technique…
