Reversible non-equilibrium phase transformation in amorphous germanium

Yang Huang, Marek MihalkoviÄ, Michael Widom

First principles molecular dynamics simulations of germanium reveal a reversible liquid-glass transition below the equilibrium melting point with a wide hysteresis loop. Direct cal…

First-Principles Thermodynamics of Al $_{10}$ V: An Analytical Treatment of Localized Anharmonic Modes

Hassan Y. Albuhairan, Marek MihalkoviÄ, Michael Widom

Many complex intermetallic structures possess cage-like environments that can host additional guest atoms. In Al $_{10}$ V, these atoms give rise to low-frequency, localized vibratio…

First principles investigation of phase stability in the B-Pt alloy system

Michael Widom

The B-Pt alloy system contains several Pt-rich phases exhibiting complex structures, many with partial site occupation. It also exhibits a deep (nearly 1000 degrees C) eutectic. We…
