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…

Magnetic Interaction in Insulating Cuprates
Yoshiaki Mizuno, Takami Tohyama, Sadamichi Maekawa
We examine two-spin (2S) and cyclic four-spin (4S) magnetic interactions in insulating ladder and two-dimensional (2D) cuprates. By a comparison of eigenstates between d-p and Heis…
