Analytic continuation via domain knowledge free machine learning
TL;DR: The machine-learning-based approach to analytic continuation not only provides the more accurate spectrum than the conventional methods in terms of peak positions and heights, but is also more robust against the noise which is the required key feature for any continuation technique to be successful.
Direct experimental observation of the molecular J eff = 3/2 ground state in the lacunar spinel GaTa 4 Se 8 .

TL;DR: Direct experimental evidence of the Jeff = 3/2 state in GaTa4Se8 is reported by means of excitation spectra of resonant inelastic X-ray scattering at the Ta L3 and L2 edges, manifesting the realization of the molecular Jeff’s ground state.
Sr 2 Ir 1 − x Rh x O 4 ( x 0.5 ) : An inhomogeneous j eff = 1 2 Hubbard system

TL;DR: In this article, the spin-orbit coupling of iridium and rhodium sites was investigated using the branching ratios of the $L$-edge isotropic x-ray absorption spectra.
Maximum quantum entropy method
Jae-Hoon Sim,Myung Joon Han +1 more
TL;DR: In this article, a maximum entropy method for analytic continuation is extended by introducing quantum relative entropy, which is formulated in terms of matrix-valued functions and therefore invariant under arbitrary unitary transformation of input matrix.
