Motivated by the current high interest in the field of warm dense matter research, in this
article we review the uniform electron gas (UEG) at finite temperature and over a broad …

Hydrogen and helium are the most abundant elements in the Universe. They are also, in
principle, the most simple. Nonetheless, they display remarkable properties under extreme …

Producing metallic hydrogen has been a great challenge in condensed matter physics.
Metallic hydrogen may be a room-temperature superconductor and metastable when the …

We present an overview of the variational and diffusion quantum Monte Carlo methods as
implemented in the casino program. We particularly focus on developments made in the last …

As the name implies, Monte Carlo (MC) methods employ random numbers to solve
problems. The range of problems that may be treated by MC is substantial; these include …

Molecular hydrogen is expected to exhibit metallic properties under megabar pressures.
This metal is predicted to be superconducting with a very high critical temperature, T c, of …

Using quantum simulation techniques based on either density functional theory or quantum
Monte Carlo, we find clear evidence of a first-order transition in liquid hydrogen, between a …

Quantum Monte Carlo (QMC) is a powerful method to calculate accurate energies and
forces for molecular systems. In this work, we demonstrate how we can obtain accurate QMC …

Simulations of materials behavior are an important component of materials science
research, partly because measurements are indirect, requiring theoretical interpretation, and …

Quantum Monte Carlo (QMC) is a family of stochastic methods for solving quantum many-
body problems such as the stationary Schrödinger equation. The review introduces basic …
