Ye. Lozovik et Va. Mandelshtam, ASYMPTOTIC PROPERTIES OF PATH-INTEGRAL MONTE-CARLO CALCULATIONS, Nuovo cimento della Societa italiana di fisica. B, Relativity, classical and statistical physics, 109(6), 1994, pp. 575-581
We analyse the problem of the convergence and errors in calculations o
f the path integral in quantum Monte Carlo method. The behaviours of d
ifferent estimators of potential, kinetic and total energies are compa
red through the analysis of the corresponding correlation functions.
