Neural Network Representations of Multiphase Equations of State

George A. Kevrekidis, Daniel A. Serino, Alexander Kaltenborn +3

Equations of State model relations between thermodynamic variables and are ubiquitous in scientific modelling, appearing in modern day applications ranging from Astrophysics to Cli…

Signatures of Stripe Phases in Hole Doped

Ya-Sha Yi, Zhi-Gang Yu, A. R. Bishop +1

We study nickelate-centered and oxygen-centered stripe phases in doped LaNiO materials. We use an inhomogeneous Hartree-Fock and random-phase approximation approach inc…

Quantum Breathers in Electron-phonon Systems

W. Z. Wang, A. R. Bishop, J. T. Gammel +1

Quantum breathers are studied numerically in several electron-phonon coupled finite chain systems, in which the coupling results in intrinsic nonlinearity but with varying degrees…

Modeling Metallic Microstructure Using Moving Finite Elements

Andrew Kuprat, J. Tinka Gammel

We present an efficient method for anealing 3d metallic grains using Gradient Weighted Moving Finite Elements (GWMFE). The initial grain microstructure is generated from Monte-Carl…

Quantum Breathers in a Nonlinear Lattice

W. Z. Wang, J. Tinka Gammel, A. R. Bishop +1

We study nonlinear phonon excitations in a one-dimensional quantum nonlinear lattice model using numerical exact diagonalization. We find that multi-phonon bound states exist as ei…

Pressure Tuning of the Charge Density Wave in the Halogen-Bridged Transition-Metal (MX) Solid

G. S. Kanner, J. Tinka Gammel, S. P. Love +3

We report the pressure dependence up to 95 kbar of Raman active stretching modes in the quasi-one-dimensional MX chain solid . The data indicate that a predicted…
