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. However, this process faces a fundamental challenge: it is an ill-posed

We measured the electrical resistivity and the $^{121}$Sb nuclear quadrupole resonance (NQR) spectra of La$_3$TiSb$_5$, which is a nonmagnetic reference system for a locally noncentrosymmetric antiferromagnet Ce$_3$TiSb$_5$, in order to determine its
