Many things in the natural world are geometrically chiral, meaning they cannot be superimposed onto their mirror image. Think hands — right and left hands are mirror images but if you transplanted a r...
Weak Measurements of Light Chirality with a Plasmonic Slit
Weak Measurements of Light Chirality Plasmonic Slit Optics
font style='font-size:12px;'>
2012/4/19
We examine, both experimentally and theoretically, an interaction of tightly focused polarized light with a slit on a metal surface supporting plasmon-polariton modes. Remarkably, this simple system c...
Chirality control by electric field in periodically poled MgO-doped lithium niobate
Chirality control electric field periodically poled MgO-doped lithium niobate Optics

2012/4/19
We study the chirality of periodically poled MgO-doped lithium niobate (MgO:PPLN) by electro-optic (EO) effect. It shows that optical propagation is reciprocal in MgO:PPLN when quasi-phase-matching (Q...

We investigate several important properties of multi-band superconductors. They are time-reversal symmetry breaking, chirality and fractional quantum flux vortices in three-band superconductors. The B...
Electroluminescence from chirality-sorted (9,7)-semiconducting carbon nanotube devices
Electroluminescence chirality-sorted semiconducting carbon nanotube devices
font style='font-size:12px;'>
2011/8/18
Abstract: We have measured the electroluminescence and photoluminescence of (9,7) semiconducting carbon nanotube devices and demonstrate that the electroluminescence wavelength is determined by the na...

We develop a theory for the temperature and density dependence of phonon-limited resistivity
(T ) in bilayer and multilayer graphene, and compare with the corresponding monolayer result. For the uns...
A measure for the chirality of triangles

font style='font-size:12px;'>
2010/11/8
A measure for the description of the chirality of triangles is introduced. The measure $X\delta$ is zero for triangles with at least one mirror axe, i.e. equilateral or isosceles triangles, and positi...
