Quantum Evaporation from Superfluid 4He
The quantum evaporation experiments of Brown and Wyatt have been re-analysed in the light of a recent measurement of the high-energy phonon spectrum created by a pulse-heated thin film. Two sources of systematic error become significant at the level of the precision required by this new analysis: firstly, in the detector position which is recalibrated by using large-angle roton evaporation; and...
متن کاملViscoplastic tearing of polyethylene thin film
Recent advances in non-contact strain measurement techniques and large-strain constitutive modeling of the Linear Low-Density Polyethylene film used in NASA Superpressure balloons, StratoFilm 420, are combined to provide a novel measurement technique for the tear propagation critical value of the J-integral. Previously these measurements have required complex test configurations and procedures....
متن کاملSuperfluid 4He quantum interference grating.
We report the first observation of quantum interference from a grating structure consisting of four weak link junctions in superfluid 4He. We find that an interference grating can be implemented successfully in a superfluid matter wave interferometer to enhance its sensitivity while trading away some of its dynamic range. We also show that this type of device can be used to measure absolute qua...
متن کاملNumerical Portrait of a Relativistic Thin Film Bcs Superfluid
We present results of numerical simulations of the 2+1d Nambu – Jona-Lasinio model with a non-zero baryon chemical potential μ including the effects of a diquark source term. Diquark condensates, susceptibilities and masses are measured as functions of source strength j. The results suggest that diquark condensation does not take place in the high density phase μ > μc, but rather that the conde...
متن کاملUltrafast polarization switching in thin-film ferroelectrics
We present an experimental approach to study the ultrafast polarization switching dynamics in thin-film ferroelectrics. A semiconductor photoconductive switch with femtosecond laser illumination is used as a ‘‘pulse generator’’ to produce jitter-free, sub-100 ps rise time step-function-like electrical pulses. Quantitative measurements yield a polarization switching time, ts , of ;220 ps when me...
