Design of high-order short-time approximations as a problem of matching the covariance of a Brownian motion
Cristian Predescu
One of the outstanding problems in the numerical discretization of the Feynman-Kac formula calls for the design of arbitrary-order short-time approximations that are constructed in…
Thermodynamics and equilibrium structure of Ne_38 cluster: Quantum Mechanics versus Classical
Cristian Predescu, Pavel A. Frantsuzov, Vladimir A. Mandelshtam
The equilibrium properties of classical LJ_38 versus quantum Ne_38 Lennard-Jones clusters are investigated. The quantum simulations use both the Path-Integral Monte-Carlo (PIMC) an…
Moments of spectral functions: Monte Carlo evaluation and verification
Cristian Predescu
The subject of the present study is the Monte Carlo path-integral evaluation of the moments of spectral functions. Such moments can be computed by formal differentiation of certain…
