Strong-coupling formula for momentum-dependent susceptibilities in dynamical mean-field theory
Junya Otsuki, Kazuyoshi Yoshimi, Hiroshi Shinaoka +1
Computing momentum-dependent susceptibilities in the dynamical mean-field theory (DMFT) requires solving the Bethe-Salpeter equation, which demands large computational cost. Exploi…
irbasis: Open-source database and software for intermediate-representation basis functions of imaginary-time Green's function
Naoya Chikano, Kazuyoshi Yoshimi, Junya Otsuki +1
The open-source library, irbasis, provides easy-to-use tools for two sets of orthogonal functions named intermediate representation (IR). The IR basis enables a compact representat…
Overcomplete compact representation of two-particle Green's functions
Hiroshi Shinaoka, Junya Otsuki, Kristjan Haule +4
Two-particle Green's functions and the vertex functions play a critical role in theoretical frameworks for describing strongly correlated electron systems. However, numerical calcu…
