Liu, Feng | First-principles studies on structural properties of β-cristobalite | The structure of β-cristobalite has been studied through a first-principles total-energy minimization in the local-density approximation using a Car-Parrinello-type algorithm combined with the Vanderbilt ultrasoft pseudopotential scheme. It was found that the hypothetical ordered structure propose... | First-principles; Car-Parrinello-type algorithm | 1993-05 |

DeTar, Carleton | Tunneling and the spectrum of the Potts model | The three-dimensional, three-state Potts model is studied as a paradigm for high-temperature quantum chromodynamics. In a high-statistics numerical simulation using a Swendson-Wang algorithm, we study cubic lattices of dimension as larger as 643 and measure correlation functions on long lattices of ... | Potts model; Tunneling; Transfer matrix; Phase transitions | 1993-05 |
