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…

Quantum phase transitions in the dimerized extended Bose-Hubbard model
Koudai Sugimoto, Satoshi Ejima, Florian Lange +1
We present an unbiased numerical density-matrix renormalization group study of the one-dimensional Bose-Hubbard model supplemented by nearest-neighbor Coulomb interaction and bond…
