Etched Bragg reflectors as two-dimensional photonic crystals (2004)
Journal Article
Beggs, D., Kaliteevski, M., & Abram, R. (2004). Etched Bragg reflectors as two-dimensional photonic crystals. Journal of Physics: Condensed Matter, 16(45), 8093-8099. https://doi.org/10.1088/0953-8984/16/45/031

We have studied GaAs/oxidized AlAs (AlOx) Bragg reflectors with etched air grooves running parallel to the growth direction. Such structures possess periodic modulation of the refractive index in two dimensions, and we have found that they have a pho...

Journal Article
Cheung, D., Clark, S., & Wilson, M. (2004). Calculation of flexoelectric coefficients for a nematic liquid crystal by atomistic simulation. The Journal of Chemical Physics, 121(18), 9131-9139. https://doi.org/10.1063/1.1802231

Equilibrium molecular dynamics calculations have been performed for the liquid crystal molecule n-4-(trans-4-n-pentylcyclohexyl)benzonitrile (PCH5) using a fully atomistic model. Simulation data have been obtained for a series of temperatures in the... Read More about Calculation of flexoelectric coefficients for a nematic liquid crystal by atomistic simulation.

Variable temperature neutron powder diffraction study to determine the magnetic interactions in Sr(2)LnRuO(6) (Ln = Ho and Tb). Journal of Physics: Condensed Matter, 16(43), 7611-7624. https://doi.org/10.1088/0953-8984/16/43/005

Neutron powder diffraction has been used to study the two title compounds, Sr2HoRuO6 and Sr2TbRuO6, in order to determine the crystal and magnetic structures of the materials. Both materials have a distorted double perovskite structure and at tempera...

H.E.S.S.—the high energy stereoscopic system—is a new system of large atmospheric Cherenkov telescopes for GeV/TeV astronomy. Each of the four telescopes of 107 m2 mirror area is equipped with a 960-pixel photomultiplier-tube camera. This paper descr... Read More about Calibration of cameras of the H.E.S.S. detector.

We introduce the NOAO Fundamental Plane Survey (NFPS), a wide-field imaging/spectroscopic study of rich, low-redshift galaxy clusters. The survey targets X-rayselected clusters at 0.010 < z < 0.067, distributed over the whole sky, with imaging and sp... Read More about NOAO fundamental plane survey. I.

An XMM-Newton view of the luminous X-ray source population of M101. (2004)
Journal Article
Jenkins, L., Roberts, T., Warwick, R., Kilgard, R., & Ward, M. (2004). An XMM-Newton view of the luminous X-ray source population of M101. Memorie Della Società Astronomica Italiana, 75(3),

We present the first results of an XMM n EPIC observation of the luminous X-ray source population in the face-on supergiant spiral galaxy M101. We have studied the X-ray spectral and temporal properties of the most luminous sources in M101 at the tim... Read More about An XMM-Newton view of the luminous X-ray source population of M101..

Comparison of subspace and arx models of a waveguide's terahertz transient response after optimal wavelet filtering (2004)
Journal Article

Comparison of subspace and arx models of a waveguide's terahertz transient response after optimal wavelet filtering. IEEE Transactions on Microwave Theory and Techniques, 52(10), 2409-2419. https://doi.org/10.1109/tmtt.2004.835983

A quasi-optical deembedding technique for characterizing waveguides is demonstrated using wide-band time-resolved terahertz spectroscopy. A transfer function representation is adopted for the description of the signal in the input and output port of...

We subject a falling cloud of cold cesium atoms to periodic kicks from a sinusoidal potential created by a vertical standing wave of laser light. By controllably accelerating the potential, we show quantum accelerator mode dynamics to be highly sensi... Read More about Gravity-sensitive quantum dynamics in cold atoms.
