-VAE: Curvature regularized variational autoencoders for uncovering emergent low dimensional geometric structure in high dimensional data
Jason Z. Kim, Nicolas Perrin-Gilbert, Erkan Narmanli +5
Natural systems with emergent behaviors often organize along low-dimensional subsets of high-dimensional spaces. For example, despite the tens of thousands of genes in the human ge…
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…
Dislocation Kinks in Copper: Widths, Barriers, Effective Masses, and Quantum Tunneling
Tejs Vegge, James P. Sethna, Siew-Ann Cheong +3
We calculate the widths, migration barriers, effective masses, and quantum tunneling rates of kinks and jogs in extended screw dislocations in copper, using an effective medium the…
Dislocation Mobility in Two-dimensional Lennard-Jones Material
N. Bailey, J. Sethna, C. Myers
In seeking to understand at a microscopic level the response of dislocations to stress we have undertaken to study as completely as possible the simplest case: a single dislocation…
