Robust analytic continuation using sparse modeling approach imposed by semi-positive definiteness for multi-orbital systems

Yuichi Motoyama, Hiroshi Shinaoka, Junya Otsuki +1

Analytic continuation (AC) from imaginary-time Green's function to spectral function is essential in the numerical analysis of dynamical properties in quantum many-body systems. Ho…
