Monte Carlo Hamiltonian: Inverse Potential
Xiang-Qian Luo, Xiao-Ni Cheng, Helmut Kroger
Abstract
The Monte Carlo Hamiltonian method developed recently allows to investigate ground state and low-lying excited states of a quantum system, using Monte Carlo algorithm with importance sampling. However, conventional MC algorithm has some difficulties when applying to inverse potentials. We propose to use effective potential and extrapolation method to solve the problem. We present examples from the hydrogen system.
