Abstract (in Japanese) (See Japanese page) 
(in English) We study ground-state and dynamical properties in the one-dimensional cluster model with several interactions. First, we determine the ground-state phase diagram by using the in finite time-evolving block decimation method and the exact diagonalization. Each phase is characterized by the entanglement spectrum and the correlation functions. Next, we investigate dynamical properties during an interaction sweep through a critical point. After a slow sweep across the critical point, spatially periodic structures appear in the entanglement entropy and the string correlation function. It is shown that the periodicities result from the Bogoliubov quasiparticles generated near the critical point.
