Parameterization of the Stoner-Wohlfarth model of magnetic hysteresis
Nikolai A. Zarkevich, Cajetan Ikenna Nlebedim, R. William McCallum
The Stoner-Wohlfarth is the most used model of magnetic hysteresis, but its computation is time-consuming. We use machine learning to approximate piecewise this model by easy-to-co…

A grand challenge underlies the entire field of topology-enabled quantum logic and information science: how to establish topological control principles driven by quantum coherence…
Vacancy-mediated complex phase selection in high entropy alloys
Prashant Singh, Srinivasa Thimmaiah, Bryce Thoeny +4
Phase selection in Ti-Zr-Hf-Al high-entropy alloys was investigated by in-situ high-energy Xray diffraction, single-crystal Xray diffraction, and density-functional theory ba…
In situ quantitative study of plastic strain-induced phase transformations under high pressure: Example for ultra-pure Zr
K. K. Pandey, Valery I. Levitas
The first in situ quantitative synchrotron X-ray diffraction (XRD) study of plastic strain-induced phase transformation (PT) has been performed on PT in ultra-pure, strongly…
ART: A machine learning Automated Recommendation Tool for synthetic biology
Tijana Radivojević, Zak Costello, Kenneth Workman +1
Biology has changed radically in the last two decades, transitioning from a descriptive science into a design science. Synthetic biology allows us to bioengineer cells to synthesiz…
First-principles concentration-wave approach to predict incipient order in high-entropy alloys: case of TiCrFeNiAl
Prashant Singh, A. V. Smirnov, Aftab Alam +1
Multi-principal-element alloys, including high-entropy alloys, experience segregation or partially-ordering as they are cooled to lower temperatures. For TiCrFeNiAl,…
Predicting Complex Relaxation Processes in Metallic Glass
Yang Sun, Si-Xu Peng, Qun Yang +5
Relaxation processes significantly influence the properties of glass materials. However, understanding their specific origins is difficult, even more challenging is to forecast the…

MFiX-Exa is a new code being actively developed at Lawrence Berkeley National Laboratory and the National Energy Technology Laboratory as part of the U.S. Department of Energy's Ex…
Bose-Einstein condensation of triplons close to the quantum critical point in the quasi-one-dimensional spin- antiferromagnet NaVOPO
Prashanta K. Mukharjee, K. M. Ranjith, B. Koo +7
Structural and magnetic properties of a quasi-one-dimensional spin- compound NaVOPO are explored by x-ray diffraction, magnetic susceptibility, high-field magnetization, s…
Compressive performance and crack propagation in Al alloy/Ti2AlC composites
D. A. H. Hanaor, L. Hu, W. H. Kan +4
Composite materials comprising a porous Ti2AlC matrix and Al 6061 alloy were fabricated by a current-activated pressure assisted melt infiltration process. Coarse, medium and fine…
A diffraction paradox: An unusually broad diffraction background signals ideal graphene
S. Chen, M. Horn von Hoegen, P. A. Thiel +1
The realization of the unusual properties of 2-d materials requires the formation of large domains of single layer thickness, extending over the mesoscale. It is found that the for…
