Temperature Dependence of Spin Correlation and Charge Dynamics in the Stripe Phase of High-T_c Superconductors
Y. Shibata, T. Tohyama, S. Maekawa
We examine the temperature dependence of the electronic states in the stripe phase of high-Tc cuprates by using the t-J model with a potential that stabilizes vertical charge strip…

Spin Liquid State around a Doped Hole in Insulating Cuprates
T. Tohyama, Y. Shibata, S. Maekawa +3
The numerically exact diagonalization study on small clusters of the t-J model with the second- and third- neighbor hopping terms shows that a novel spin liquid state is realized a…

Effect of magnetic frustration on single-hole spectral function in the t-t'-t''-J model
Y. Shibata, T. Tohyama, S. Maekawa
We examine the effect of the magnetic frustration J' on the single-hole spectral function in the t-t'-t''-J model. At zero temperature, the exact diagonalization (ED) and the self-…
