Journal ArticleDOI
High-pressure low-symmetry phases of cesium halides.
TL;DR: The analysis reveals the essential role played by the phonon-strain coupling in stabilizing the orthorhombic phase and in making the corresponding transition first-order.
Book ChapterDOI
A Performance Study of Quantum ESPRESSO’s PWscf Code on Multi-core and GPU Systems
Joshua Romero,Everett Phillips,Gregory Ruetsch,Massimiliano Fatica,Filippo Spiga,Paolo Giannozzi +5 more
TL;DR: The porting of PWscf (Plane-Wave Self Consistent Field), a key component of the Quantum ESPRESSO open-source suite of codes for materials modeling, to GPU systems using CUDA Fortran is described.
Book ChapterDOI
First-Principles Molecular Dynamics
TL;DR: In this paper, density functional theory (DFT) is used to derive macroscopic observables under the controlled condition of a "computational experiment" and with a predictive power rooted in the quantum-mechanical description of interacting atoms and electrons.
Journal ArticleDOI
Phonon Softening and High-Pressure Low-Symmetry Phases of Cesium Iodide
TL;DR: It is demonstrated that the cubic-to-orthorhombic transition recently observed to occur slightly below 20 GPa is driven by the softening of an acoustic phonon at the M point of the Brillouin zone.

High-Pressure Low-Symmetry Phases of Cesium Halides from First Principle Techniques
TL;DR: In this paper, the relative stability of different high-pressure phases of various Cesium Halides is studied from first principles and analyzed using the Landau theory of phase transitions using an acoustic phonon at the M point of the Brillouin zone.
