Coupled Electron-Ion Monte Carlo calculations of atomic hydrogen
We present a new Monte Carlo method which couples Path Integral for finite temperature protons with Quantum Monte Carlo for ground state electrons, and we apply it to metallic hydrogen for pressures beyond molecular dissociation. This method fills the gap between high temperature electron-proton Path Integral and ground state Diffusion Monte Carlo methods. Our data exhibit more structure and hi...
متن کاملCoupled electron-ion monte carlo calculations of dense metallic hydrogen.
We present an efficient new Monte Carlo method which couples path integrals for finite temperature protons with quantum Monte Carlo calculations for ground state electrons, and we apply it to metallic hydrogen for pressures beyond molecular dissociation. We report data for the equation of state for temperatures across the melting of the proton crystal. Our data exhibit more structure and higher...
متن کاملMonte Carlo calculations of low energy positrons in silicon
The penetration of charged particles through matter is determined by the outcomes of countless Coulomb collisions with atoms and atomic electrons. It is a useful schematization to classify these collisions as soft and hard. Soft collisions, with impact parameters large compared to atomic dimensions are extremely numerous, and give rise to small energy losses and deflections. Hard collisions, wi...
متن کاملQuantum free-energy calculations: Optimized Fourier path-integral Monte Carlo computation of coupled vibrational partition functions
The Fourier coefficient path-integral representation of the quantum density matrix is used to carry out direct, accurate calculations of coupled vibrational partition functions. The present implementation of the Fourier path-integral method incorporates two noteworthy features. First, we use a Gaussian in Fourier space as a probability density function, which is sampled using the Box-Muller alg...
متن کاملMonte Carlo calculations
A Monte Carlo simulation using the PRESTA version of the EGS4 code has been employed as an investigative tool to calculate the absorbed dose in water close to 192Ir wire implants. It has been shown that a treatment planning system, such as GE Target II, using the Sievert integral and the Meisberger polynomial is only able to reproduce the Monte Carlo results at radial distances of 1 mm and fart...
