RESPACK: An ab initio tool for derivation of effective low-energy model of material
Kazuma Nakamura, Yoshihide Yoshimoto, Yusuke Nomura +6
RESPACK is a first-principles calculation software for evaluating the interaction parameters of materials and is able to calculate maximally localized Wannier functions, response f…
Charge and spin response functions on a quantum computer: applications to molecules
Taichi Kosugi, Yu-ichiro Matsushita
We propose a scheme for the construction of charge and spin linear-response functions of an interacting electronic system via quantum phase estimation and statistical sampling on a…
A Parallel Computing Method for the Coupled-Cluster Singles and Doubles
Takumi Yamashita, Taichi Kosugi, Yu-ichiro Matsushita +1
In this paper, we present a parallel computing method for the coupled-cluster singles and doubles (CCSD) in periodic systems. The CCSD in periodic systems solves simultaneous equat…
Construction of Green's functions on a quantum computer: applications to molecular systems
Taichi Kosugi, Yu-ichiro Matsushita
We propose a scheme for the construction of one-particle Green's function (GF) of an interacting electronic system via statistical sampling on a quantum computer. Although the non-…
Wannier interpolation of one-particle Green's functions from coupled-cluster singles and doubles (CCSD)
Taichi Kosugi, Yu-ichiro Matsushita
We propose two schemes for interpolation of the one-particle Green's function (GF) calculated within coupled-cluster singles and doubles (CCSD) method for a periodic system. They u…
One-particle Green's function of interacting two electrons using analytic solutions for a three-body problem: comparison with exact Kohn--Sham system
Taichi Kosugi, Yu-ichiro Matsushita
For a three-electron system with finite-strength interactions confined to a one-dimensional harmonic trap, we solve the Schroedinger equation analytically to obtain the exact solut…
