Experimental Observation of Entanglement Duality for Identical Particles
entanglement duality quantum indistinguishability quantum mechanics
2016/1/22
It was shown recently that entanglement of identical particles has a feature called dualism (Bose and Home 2013 Phys. Rev. Lett. 110 140404), which is funda-mentally connected with quantum indistingui...
Observation of Unusual Mass Transport in Solid hcp 4He
Stop the capillary constant temperature superfluid solid atoms the melting curve
2014/12/20
Solid 4He has been created off the melting curve by growth at a nearly constant mass via the “blocked capillary” technique and growth from the 4He superfluid at constant temperature. The experimental ...
Observation of mass transport through solid 4He
Superfluid helium cells solid temperature
2014/12/19
By use of an experimental design that provides for superfluid helium in contact with bulk hcp 4He off the melting curve, we have observed the dc transport of mass through a cell filled with solid 4He ...
Observation of thermomechanical equilibration in the presence of a solid 4He conduit
Thermodynamics fluid quartz glass rod temperature difference quantitative thermodynamic effect the superfluid helium
2014/12/19
We observe a thermomechanical effect when a chemical-potential difference is created by a temperature difference imposed between two liquid reservoirs connected to each other through Vycor rods in ser...
Quantum Interferometry and Correlated Two-Electron Wave-Packet Observation in Helium
Quantum Interferometry Correlated Two-Electron Wave-Packet Observation Helium Atomic Physics
2012/5/17
The concerted motion of two or more bound electrons governs atomic and molecular non-equilibrium processes and chemical reactions. It is thus a long-standing scientific dream to measure the dynamics o...
Observation of a rotational transition in trapped and sympathetically cooled molecular ions
Observation rotational transition trapped sympathetically cooled molecular ions
2012/2/28
We demonstrate rotational excitation of molecular ions that are sympathetically cooled by laser-cooled atomic ions to a temperature as low as ca. 10 mK. The molecular hydrogen ions HD+ and the fundame...
Observation of Superfluorescence from a Spontaneous Coherence of Excitons in ZnTe Crystal: Evidence for Bose-Einstein Condensation of Excitons?
Superfluorescence Spontaneous Coherence Excitons ZnTe Crystal Bose-Einstein Condensation
2011/8/11
Abstract: Superfluorescence (SF) is the emission from a dense coherent system in population inversion, formed from an initially incoherent ensemble. This is characterised by an induction time (t_D) fo...
Observation of (N2)2 dimers in free nitrogen and argon-nitrogen clusters
(N2)2 dimers free nitrogen argon-nitrogen clusters
2011/8/4
Abstract: Supersonic-jet luminescence spectroscopy was applied to study vibronic transitions in icosahedral N2 and Ar-N2 clusters having from 100 to 400 particles per cluster. In the case of mixed Ar-...
Observation of second-order hyper-Raman generation in LiNbO3 whispering-gallery mode disk resonators
Observation second-order hyper-Raman generation LiNbO3 whispering-gallery mode disk resonators
2011/8/4
Abstract: In this manuscript we report experimental demonstration of nonlinear frequency conversion at several optical frequencies in a whispering-gallery mode resonator (WGMR). Due to the enhancement...
Experimental observation of the steady - oscillatory transition in a cubic lid-driven cavity
Experimental observation oscillatory transition cubic lid-driven cavity Fluid Dynamics
2011/8/2
Abstract: Particle image velocimetry is applied to the lid-driven flow in a cube to validate the numerical prediction of steady - oscillatory transition at lower than ever observed Reynolds number. Ex...
y Dispersion Analysis for the Hayabusa Spacecraft using Ground Based Optical Observation
astrometry — celestial mechanics — Hayabusa — orbit determination — space vehicles
2011/9/8
Hayabusa asteroid explorer successfully released the sample capsule to Australia on June 13, 2010. Since the Earth reentry phase of sample return was critical, many backup plans for predicting the lan...

dielectric function Fano resonance gold nanorod plasmon resonance scattering substrate
2014/5/28
Fano resonances in plasmonic nanostructures, characterized by their asymmetric resonance spectral profile, are currently attracting much interest due to their potential applications in biological sens...
