Coherent phase-matched VUV generation by field-controlled bound states
Little attention has been devoted to development and characterization of below-threshold harmonic sources, which are critical for extending time-resolved photoemission spectroscopy to megahertz repetition rate...

Constraints in Noncommutative Chern-Simons Mechanics and Hall Effect
We study noncommutative Chern-Simons mechanics and noncommutative Hall effect by Dirac theory in this paper. The magnetic field is introduced by means of minimal coupling. We show that the constraint set will ...

Flat dielectric grating reflectors with focusing abilities
Sub-wavelength dielectric gratings have emerged recently as a promising alternative to distributed Bragg reflection dielectric stacks for broadband, high-reflectivity filtering applications. Such a grating str...
