Optically Induced Sieve Effect for Nanoparticles near a Nanofiber Taper

Doubly curved nanofiber-reinforced optically transparent composites

Doubly curved nanofiber-reinforced optically transparent composites with low thermal expansion of 15 ppm/k are prepared by hot pressing vacuum-filtered Pickering emulsions of hydrophobic acrylic resin monomer, hydrophilic chitin nanofibers and water. The coalescence of acrylic monomer droplets in the emulsion is prevented by the chitin nanofibers network. This transparent composite has 3D shape...

Atoms near an Optical Nanofiber

Title of thesis: TRANSMISSION SPECTRA OF RB ATOMS NEAR AN OPTICAL NANOFIBER. Burkley Delesdernier Patterson, Master of Science, 2016 Dissertation directed by: Professor Luis A. Orozco Department of Physics We present measurements of the transmission spectra of Rb atoms at 780 nm in the vicinity of a nanofiber. A uniform distribution of fixed atoms around a nanofiber should produce a spectrum th...

Optically induced spin-Hall effect in atoms.

We propose an optical means to realize the spin-Hall effect (SHE) in a neutral atomic system by coupling the internal spin states of atoms to radiation. The interaction between the external optical fields and the atoms creates effective magnetic fields that act in opposite directions on "electrically" neutral atoms with opposite spin polarizations. This effect leads to a Landau level structure ...

Effect of Rail Corrugation on the Amount of Train Induced Vibrations near a Historical Building

The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...
