Fracture in Mode I using a Conserved Phase-Field Model

L. O. Eastgate, J. P. Sethna, M. Rauscher +3

We present a continuum phase-field model of crack propagation. It includes a phase-field that is proportional to the mass density and a displacement field that is governed by linea…

Improved tensor-product expansions for the two-particle density matrix

Gábor Csányi, Stefan Goedecker, T. A. Arias

We present a new density-matrix functional within the recently introduced framework for tensor-product expansions of the two-particle density matrix. It performs well both for the…

Scaling in Plasticity-Induced Cell-Boundary Microstructure: Fragmentation and Rotational Diffusion

James P. Sethna, Valerie R. Coffman, Eugene Demler

We develop a simple computational model for cell boundary evolution in plastic deformation. We study the cell boundary size distribution and cell boundary misorientation distributi…

Accurate Calculations of the Peierls Stress in Small Periodic Cells

D. E. Segall, T. A. Arias, Alejandro Strachan +1

The Peierls stress for a [111]-screw dislocation in bcc Tantalum is calculated using an embedded atom potential. More importantly, a method is presented which allows accurate calcu…

Ferromagnetic instabilities in atomically-thin lithium and sodium wires

A. Bergara, J. B. Neaton, N. W. Ashcroft

Using density functional theory the ground state structural, electronic, and magnetic properties of monatomic lithium and sodium chains with low average density are investigated. A…

Porous silicon formation and electropolishing

Markus Rauscher, Herbert Spohn

Electrochemical etching of silicon in hydrofluoride containing electrolytes leads to pore formation for low and to electropolishing for high applied current. The transition between…
