Renormalized density matrix downfolding: A rigorous framework in learning emergent models from ab initio many-body calculations
Yueqing Chang, Sonali Joshi, Lucas K. Wagner
We present a generalized framework, renormalized density matrix downfolding (RDMD), to derive systematically improvable, highly accurate, and nonperturbative effective models from…
Quantification of electron correlation for approximate quantum calculations
Shunyue Yuan, Yueqing Chang, Lucas K. Wagner
State-of-the-art many-body wave function techniques rely on heuristics to achieve high accuracy at an attainable cost to solve the many-body Schrödinger equation. By far the most c…
Phantom Dark Ghost in Einstein-Cartan Gravity
Yu-Chiao Chang, Mariam Bouhmadi-López, Pisin Chen
A class of dynamical dark energy models is constructed through an extended version of fermion fields corresponding to phantom dark ghost spinors, which are spin one half with mass…
Planck constraints on Higgs modulated reheating of renormalization group improved inflation
Yi-Fu Cai, Yu-Chiao Chang, Pisin Chen +2
Within the framework of RG improved inflationary cosmology motivated by asymptotically safe gravity, we study the dynamics of a scalar field which can be interpreted as the Higgs f…
