Equation of State and First Principles Prediction of the Vibrational Matrix Shift of Solid Parahydrogen
Alexander Ibrahim, Lecheng Wang, Tom Halverson +2
We generate the equation of state (EOS) of solid parahydrogen using a path-integral Monte Carlo (PIMC) simulation based on a highly accurate first-principles adiabatic hindered rot…
