The façades of buildings are almost always organized according to Gestalt principles such as good continuation, repetition in similarity, or symmetry etc. Coding such principles in production sys...
IR color separation in transmission through gratings on (110) silicon: FTIR experiment versus theory
IR color separation transmission through gratings (110) silicon FTIR experiment versus theory Optics
2012/4/19
The phenomenon of filtering in zero-diffraction order is studied for transmission through 1D-periodic structures on a silicon wafer. Our study combines FTIR spectrometry in the range from 2.5 to 25 mi...
Interstitial BiO molecule as a center of broadband IR luminescence in bismuth-doped silica glass
Interstitial BiO molecule broadband IR luminescence bismuth-doped silica glass
2011/8/18
Abstract: IR luminescence and absorption in bismuth-doped silica glass-core fibers observed recently (see [arXiv:1106.2969v1 [physics.optics]) are argued to be caused by transitions in interstitial Bi...

UV IR Zeros Gauge Theories
2010/12/27
We unveil the general features of the phase diagram for any gauge theory with fermions transforming according to distinct representations of the underlying gauge group, at the four-loop order. We cla...
Aspects of the UV/IR correspondence : energy broadening and string fluctuations
the UV/IR correspondence energy broadening string fluctuations
2010/12/23
We show that a source which radiates in the vacuum of the strongly coupled N=4 SYM theory produces an energy distribution which, in the supergravity approximation, has the same space-time pattern as ...

Recently we studied `vanishing' horizon limits of `boosted' black D3-brane geometry \cite{hsnr}. The type IIB solutions obtained by taking these special double limits were found to describe nonrelativ...

2010/11/23
Epitaxial graphene grown on single crystal transition metal surfaces typically exhibits a moiré
pattern due to the lattice mismatch between graphene and the underlying metal surface. We use si-multan...
