Method BRA Method for General Measurement in QMC
Developed a novel reweight-annealing process in Quantum Monte Carlo (QMC) to address generic measurements, overcoming the difficulties associated with off‑diagonal measurements in strongly correlated quantum many-body systems.
Framework Generalized Reduced Density Matrix (GRDM)
A novel unified framework that simultaneously accesses the imaginary-time dynamical reduced density matrix and the standard reduced density matrix in QMC, enabling large-scale measurements of generic entanglement and correlation observables in complex interacting systems.
