Development of a Personalized Quantitative Faculty Annual Evaluation System
Faculty annual evaluation is critical for faculty career
development and department success. Our department
developed a quantitative faculty evaluation metrics system
that is more objective, consistent, flexible, personalized,
transparent, and dynamic scoring system. We have
implemented the system for 2 years and the outcomes are
very encouraging in promoting faculty and department
success.Cockrell School of Engineerin
BaFe2Se2O as an Iron-Based Mott Insulator with Antiferromagnetic Order
A new compound with a quasi-two-dimensional array of FeSe3O tetrahedra and an
orthorombic structure, namely BaFe2Se2O, has been successfully fabricated.
Experimental results show that this compound is an insulator and has an
antiferromagnetic (AF) transition at 240 K. Band structure calculation reveals
the narrowing of Fe 3d bands near the Fermi energy, which leads to the
localization of magnetism and the Mott insulating behavior. The large distances
between the Fe atoms perhaps are responsible for the characters. Linear
response calculation further indicates a strong in-plane AF exchange , this
can account for the enhanced magnetic susceptibility (which has a maximum at
about 450 K) above the Neel temperature.Comment: submitted to PRL on 2 May 2012, resubmitted to PRB on 31 May 2012,

Loophole-free Bell test for continuous variables via wave and particle correlations
We derive two classes of multi-mode Bell inequalities under local realistic
assumptions, which are violated only by the entangled states negative under
partial transposition in accordance with the Peres conjecture. Remarkably, the
failure of local realism can be manifested by exploiting wave and particle
correlations of readily accessible continuous-variable states, with very large
violation of inequalities insensitive to detector-efficiency, which makes a
strong case for a loophole-free test.Comment: 4 pages, published versio
Distinct behaviors of suppression to superconductivity in induced by Fe and Co dopants
In the superconductor LaRuSi with the Kagome lattice of Ru, we have
successfully doped the Ru with Fe and Co atoms. Contrasting behaviors of
suppression to superconductivity is discovered between the Fe and the Co
dopants: Fe-impurities can suppress the superconductivity completely at a
doping level of only 3%, while the superconductivity is suppressed slowly with
the Co dopants. A systematic magnetization measurements indicate that the doped
Fe impurities lead to spin-polarized electrons yielding magnetic moments with
the magnitude of 1.6 \ per Fe, while the electrons given by the Co
dopants have the same density of states for spin-up and spin-down leading to
much weaker magnetic moments. It is the strong local magnetic moments given by
the Fe-dopants that suppress the superconductivity. The band structure
calculation further supports this conclusion.Comment: 6 pages, 7 figure
Reply to the comment on "Loophole-free Bell test for continuous variables via wave and particle correlations"
In a recent note, Cavalcanti and Scarani (CS) constructed a counter
local-hidden-variable model to explain the violation of our inequalities in
Phys. Rev. Lett. 105, 170404 (2010). Here, we briefly discuss some issues in
response to the comments raised by CS.Comment: published versio
