What Does AFQMC Stand For?

AFQMC stands for Auxiliary Field Quantum Monte Carlo

AFQMC, or Auxiliary Field Quantum Monte Carlo, is a computational method used in quantum many-body physics and chemistry. It employs auxiliary fields to transform the complex interaction terms in quantum systems into more manageable ones, enabling efficient numerical simulations of ground and excited state properties. AFQMC is particularly valuable for studying strongly correlated electron systems and provides accurate results while effectively managing the sign problem inherent in quantum Monte Carlo simulations. It combines the rigor of quantum mechanics with advanced statistical techniques, making it a powerful tool for researchers in theoretical and computational physics.
