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
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...
Vortices and chirality in multi-band superconductors
Vortices chirality multi-band superconductors
2012/2/27
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
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...
Detection of Chirality and Mutations of Knots and Links

Abstract: In this brief presentation, we would like to present our attempts of detecting chirality and mutations from Chern-Simons gauge theory. The results show that the generalised knot invariants, ...

A mechanism for creating an enantioenrichment in the amino acids, the building blocks of the proteins, that involves global selection of one handedness by interactions between the amino acids and neut...
Chirality-dependent phonon-limited resistivity in graphenes
Chirality-dependent phonon-limited resistivity graphenes
2010/11/17
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 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...
Chirality and the origin of atmospheric humic-like substances
Chirality atmospheric humic-like substances origin
2010/2/21
Aerosol water extracts and atmospheric humic-like substances (HULIS) obtained from PM2.5-fraction aerosol samples collected in a rural/continental background environment and in an urban environment in...
