Sparse Modeling in Quantum Many-Body Problems
Junya Otsuki, Masayuki Ohzeki, Hiroshi Shinaoka +1
This review paper describes the basic concept and technical details of sparse modeling and its applications to quantum many-body problems. Sparse modeling refers to methodologies f…
Sparse sampling and tensor network representation of two-particle Green's functions
Hiroshi Shinaoka, Dominique Geffroy, Markus Wallerberger +4
Many-body calculations at the two-particle level require a compact representation of two-particle Green's functions. In this paper, we introduce a sparse sampling scheme in the Mat…
SpM: Sparse modeling tool for analytic continuation of imaginary-time Green's function
Kazuyoshi Yoshimi, Junya Otsuki, Yuichi Motoyama +2
We present SpM, a sparse modeling tool for the analytic continuation of imaginary-time Green's function, licensed under GNU General Public License version 3. In quantum Monte Carlo…
Finite Temperature Properties of Geometrically Charge Frustrated Systems
Kazuyoshi Yoshimi, Makoto Naka, Hitoshi Seo
We theoretically study finite temperature properties of interacting fermion systems under geometrical frustration in the charge degree of freedom. Physical quantities such as charg…
