Efficient world-line-based quantum Monte Carlo method without Hubbard–Stratonovich transformation
Abstract By precisely writing down the matrix element of the local Boltzmann operator ( $${\mathrm{e}}^{-\tau h}$$ e - τ h , where $$h$$ h is the Hermitian conjugate pairs of off-diagonal operators), we have proposed a new path integral formulation for quantum field theory and developed a correspond...
