Efficient World-line-based Quantum Monte Carlo Method Without Hubbard-Stratonovich Transformation
J. Wang, W. Pan, D. Y. Sun
By precisely writing down the matrix element of the local Boltzmann operator, we have proposed a new path integral formulation for quantum field theory and developed a correspondin…
