Open AccessHigh-permittivity ceramics enabled highly homogeneous zero-index metamaterials for high-directivity antennas and beyond
Zero-index metamaterials (ZIMs) can support uniform electromagnetic field distributions at any frequency, but their applications are hampered by the ZIM’s homogenization level—only 3 unit cells per free-space ...

High-excited-state splitting and multimode vibrational coupling in Mn4+-activated fluoride phosphor
Excited-states play a crucial role in the optical absorption and luminescence of solids and hence their accurate information is highly desired. Herein, we attempt to seize the excited-states information of Mn4+ i...

Light-induced frequency shifts for the lowest vibrational levels of ultracold Cs2 in the molecular pure long-range \(0_g^-\) state
The light-induced frequency shift (LIFS) of ultracold molecular ro-vibrational levels originates from the strong coupling of the atomic-scattering state and the bound-molecular state. In this paper, we present...

Isolated structures in two-dimensional optical superlattice
Overlaying commensurate optical lattices with various configurations called superlattices can lead to exotic lattice topologies and, in turn, a discovery of novel physics. In this study, by overlap** the max...

Enhanced performances of organic thin film transistors by dual interfacial modification of dielectric layer
In this paper, we demonstrate an effective method for the performance improvement of organic thin film transistors (OTFTs), in which the SiO2 dielectric layer was dually modified with polystyrene (PS) and hexame...

The local environmental dependence of properties of Luminous Red Galaxies (LRGs) from the SDSS data release 6 (SDSS6)
Using the Luminous Red Galaxy (LRG) sample of the SDSS Data Release 6, we investigate the dependence of LRG properties on the local environment. For each LRG, the local three-dimensional density within the dis...

Correlations among color, morphology, and luminosity for the luminous red galaxy (LRG) sample of the SDSS data release 5
We have investigated the correlations among color, morphology and luminosity for all LRGs, cut I LRGs, cut II LRGs, and Main galaxies that are also classified as LRGs. It is found that the morphology of LRGs i...
