Reversible modulation and ultrafast dynamics of THz resonances in strongly photoexcited metamaterials

I. Chatzakis, L. Luo, J. Wang +4

We demonstrate an ultrafast reversible modulation of resonant terahertz (THz) response in strongly photoexcited metamaterials. The transient spectral-temporal response of the dipol…

Structural and Magnetic Properties of Sm(Co0.7Fe0.1Ni0.12Zr0.04B0.04)7.5 Melt Spun Isotropic and Anisotropic Ribbons

Sofoklis S. Makridis, Wei Tang

We have investigated the structural and magnetic properties of Sm(Co0.7Fe0.1Ni0.12Zr0.04B0.04)7.5 melt spun ribbons. Samples were arc melted then melt spun at 37 m/s up to 55 m/s t…

Accurate and fast numerical solution of Poisson's equation for arbitrary, space-filling Voronoi polyhedra: near-field corrections revisited

Aftab Alam, Brian G. Wilson, D. D. Johnson

We present an accurate and rapid solution of Poisson's equation for space-filling, arbitrarily- shaped, convex Voronoi polyhedra (VP); the method is O(NVP), where NVP is the number…

Chemically-Mediated quantum criticality in NbFe_2

Aftab Alam, D. D. Johnson

Laves-phase Nb{1+c}Fe_{2-c} is a rare itinerant intermetallic compound exhibiting magnetic quantum criticality at c_{cr}=1.5%Nb excess; its origin, and how alloying mediates it, re…

Switching nonlinearity in a superconductor-enhanced metamaterial

Cihan Kurter, Philippe Tassin, Alexander P. Zhuravel +5

We demonstrate a nonlinear metamaterial that can be switched between low and high transmission by controlling the power level of the incident beam. The origin of this nonlinear res…

An Interactive 3D Visualization Tool for Large Scale Data Sets for Quantitative Atom Probe Tomography

Hari Dahal, Michael Stukowski, Matthias J. Graf +2

Several visualization schemes have been developed for imaging materials at the atomic level through atom probe tomography. The main shortcoming of these tools is their inability to…
