• #### Eigenmode analysis of compressional poloidal modes in a self‐consistent magnetic field ﻿

(2017)
In this study, we simulate a self‐consistent magnetic field that satisfies force balance with a model ring current that is radially localized, axisymmetric, and has anisotropic plasma pressure. We find that the magnetic ...
• #### Elastic and inelastic collisions of 6Li atoms in magnetic and optical traps ﻿

(1998)
We use a full coupled-channels method to calculate collisional properties of magnetically or optically trapped ultracold 6Li. The magnetic-field dependence of the s-wave scattering lengths of several mixtures of hyperfine ...
• #### Electric and magnetic radial diffusion coefficients using the Van Allen probes data ﻿

(2016)
ULF waves are a common occurrence in the inner magnetosphere and they contribute to particle motion, significantly, at times. We used the magnetic and the electric field data from the Electric and Magnetic Field Instrument ...
• #### Electrically tunable hot-silicon terahertz attenuator ﻿

(2014)
We have developed a continuously tunable, broadband terahertz attenuator with a transmission tuning range greater than 103. Attenuation tuning is achieved electrically, by simply changing the DC voltage applied to a heating ...

Density matrix embeddingﾠtheoryﾠ[G. Knizia and G. K.-L. Chan,ﾠPhys. Rev. Lett.109, 186404 (2012)] and density embeddingﾠtheoryﾠ[I. W. Bulik, G. E. Scuseria, and J. Dukelsky,ﾠPhys. Rev. Bﾠ89, 035140 (2014)] have recently ...
• #### Electron doping evolution of structural and antiferromagnetic phase transitions in NaFe1−xCoxAs iron pnictides ﻿

(2016)
We use transport and neutron diffraction to study the electronic phase diagram of NaFe1−xCoxAs. In the undoped state, NaFeAs exhibits a tetragonal-to-orthorhombic structural transition below Tsfollowed by a collinear ...

(2016)
We use time-of-flight (TOF) inelastic-neutron-scattering (INS) spectroscopy to investigate the doping dependence of magnetic excitations across the phase diagram of NaFe 1 − x Co x As with x = 0 , 0.0175, ...
• #### Electron doping evolution of the neutron spin resonance in NaFe1−xCoxAs ﻿

(2016)
Neutron spin resonance, a collective magnetic excitation coupled to superconductivity, is one of the most prominent features shared by a broad family of unconventional superconductors including copper oxides, iron pnictides, ...

• #### Electron-Spin Polarization at Single-Crystalline Cr and Ni Surfaces Determined with Electron-Capture Spectroscopy ﻿

(1981)
The spin polarization P of electrons at Cr and Ni surfaces is measured with electron-capture spectroscopy. With use of one-electron capture at magnetized Cr(100)-c(2×2) surfaces at 293 K (TN=310 K), P values up to -18% are ...

• #### Electronic correlation without double counting via a combination of spin projected Hartree-Fock and density functional theories ﻿

(2014)
Several schemes to avoid the double counting of correlations in methods that merge multireference wavefunctions with density functional theory (DFT) are studied and here adapted to a combination of spin-projected Hartree-Fock ...
