The ground state of the two-dimensional Hubbard model
Yoshihiro ASAI
We have studied the ground state of the two-dimensional Hubbard model by using the adaptive sampling quantum monte carlo method. We found enhancement of the d-wave correlation func…
Coupled-Cluster Approach to Electron Correlations in the Two-Dimensional Hubbard Model
Yoshihiro Asai, Hideki Katagiri
We have studied electron correlations in the doped two-dimensional (2D) Hubbard model by using the coupled-cluster method (CCM) to investigate whether or not the method can be appl…
The Ground and Low Lying Excited States of the Two-Dimensional Hubbard Model
Yoshihiro ASAI
We have studied the ground state of the two-dimensional (2D) Hubbard model by using a quantum monte method paying special attention to the shell structure effect on finite size clu…
Adaptive Sampling Approach to the Negative Sign Problem in the Auxiliary Field Quantum Monte Carlo Method
Yoshihiro ASAI
We propose a new sampling method to calculate the ground state of interacting quantum systems. This method, which we call the adaptive sampling quantum monte carlo (ASQMC) method u…
