Typicality-Based Variational Cluster Approach to Thermodynamic Properties of the Hubbard Model
Hisao Nishida, Ryo Fujiuchi, Koudai Sugimoto +1
We develop the variational-cluster-approximation method based on the thermal-pure-quantum-state approach and apply the method to the calculations of the thermodynamic properties of…

Photoinduced electron-electron pairing in the extended Falicov-Kimball model
Ryo Fujiuchi, Tatsuya Kaneko, Yukinori Ohta +1
By employing the time-dependent exact diagonalization method, we investigate the photoexcited states of the excitonic insulator in the extended Falicov-Kimball model (EFKM). We her…
