Electron ptychography reveals a ferroelectricity dominated by anion displacements

Posted by dbos Cornell

Kavli Affiliate: David A. Muller | First 5 Authors: Harikrishnan K. P., Ruijuan Xu, Kinnary Patel, Kevin J. Crust, Aarushi Khandelwal | Summary: Sodium niobate, a lead-free ferroic material, hosts delicately-balanced, competing order parameters, including ferroelectric states that can be stabilized by epitaxial strain. Here, we show that the resulting macroscopic ferroelectricity exhibits an unconventional […]

Simulation of atom trajectories in the original Stern-Gerlach experiment

Posted by dbos Caltech

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Faraz Mostafaeipour, S. Suleyman Kahraman, Kelvin Titimbo, Yixuan Tan, Lihong V. Wang | Summary: Following a comprehensive analysis of the historical literature, we model the geometry of the Stern$unicode{x2013}$Gerlach experiment to numerically calculate the magnetic field using the finite-element method. Using this calculated field and Monte […]

Inverse model for network construction: (δ(G), I’ (G)) -> G

Posted by dbos Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Wei Gao, Yaojun Chen, Hainan Zhang, , | Summary: The isolated toughness variant is a salient parameter for measuring the vulnerability of networks, which is inherently related to fractional factors (used to characterize the feasibility of data transmission). The combination of minimum degree and the corresponding tight […]

Elucidating the mechanism of helium evaporation from liquid water

Posted by dbos Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Kritanjan Polley, Kevin R. Wilson, David T. Limmer, , | Summary: We investigate the evaporation of trace amounts of helium solvated in liquid water using molecular dynamics simulations and theory. Consistent with experimental observations, we find a super-Maxwellian distribution of kinetic energies of evaporated helium. This […]
