Non-perturbative series expansion of Green's functions: The Anatomy of Resonant Inelastic X-Ray Scattering in Doped Hubbard Model
Yi Lu, Maurits W. Haverkort
We present a non-perturbative, divergence-free series expansion of Green's functions using effective operators. The method is especially suited for computing correlators of complex…

Origins of bond and spin order in rare-earth nickelate bulk and heterostructures
Yi Lu, Zhicheng Zhong, Maurits W. Haverkort +1
We analyze the charge- and spin response functions of rare-earth nickelates RNiO3 and their heterostructures using random-phase approximation in a two-band Hubbard model. The inter…
