Preparation and Characterization of Lanthanum Oxide Doped Barium Strontium Titanate Para Electric Glass Ceramics [PDF]

, 2015
(Ba0.3Sr0.7)TiO3-2SiO2-B2O3-K2O based borosilicate glass with and without 0.1 mol % La2O3 was successfully developed by melt-quench method. XRD and FTIR spectra of the glass sample confirms the formation of amorphous structure and presence of stretching ...

Demonstration of local expansion toward large-scale entangled webs

, 2010
We demonstrate an optical gate that increases the size of polarization-based W states by accessing only one of the qubits. Using this gate, we have generated three-photon and four-photon W states with fidelities $0.836\pm 0.042 $ and $0.784\pm 0.028 ...

Dielectric tuning and coupling of whispering gallery modes using an anisotropic prism

, 2016
Optical whispering gallery mode (WGM) resonators are a powerful and versatile tool used in many branches of science. Fine tuning of the central frequency and line width of individual resonances is however desirable in a number of applications including ...

Studying the universality of field induced tunnel ionization times via high-order harmonic spectroscopy

, 2014
High-harmonics generation spectroscopy is a promising tool for resolving electron dynamics and structure in atomic and molecular systems. This scheme, commonly described by the strong field approximation, requires a deep insight into the basic mechanism ...

Ultrafast photoinduced enhancement of nonlinear optical response in 15-atom gold clusters on indium tin oxide conducting film

, 2013
We show that the third order optical nonlinearity of 15-atom gold clusters is significantly enhanced when in contact with indium tin oxide (ITO) conducting film.

Stable isotope fractionation during ultraviolet photolysis of N_2O [PDF]

, 1998
The biogeochemical cycling of nitrous oxide plays an important role in greenhouse forcing and ozone regulation. Laboratory studies of N_2O:N_2 mixtures irradiated between 193–207 nm reveal a significant enrichment of the residual heavy nitrous oxide ...

A detailed description of the experimental realisation of quantum illumination protocol

, 2013
In the last years the exploitation of specific properties of quantum states has disclosed the possibility of realising tasks beyond classical limits, creating the new field of quantum technologies [1, 2, 3, 4, 5, 6, 7, 8, 9].

Multiexcitons confined within a sub-excitonic volume: Spectroscopic and dynamical signatures of neutral and charged biexcitons in ultrasmall semiconductor nanocrystals

, 2003
The use of ultrafast gating techniques allows us to resolve both spectrally and temporally the emission from short-lived neutral and negatively charged biexcitons in ultrasmall (sub-10 nm) CdSe nanocrystals (nanocrystal quantum dots).
