Cavitation Density of Superfluid Helium-4 around 1 K
An Qu, Azer Trimeche, Jacques Dupont-roc +2
Using an optical interferomertric method, the homogeneous cavitation density of superfluid helium at K is measured and found to be …
Observation of metastable hcp solid helium
Fabien Souris, Jules Grucker, Jacques Dupont-Roc +1
We have produced and observed metastable solid helium-4 below its melting pressure between 1.1 K and 1.4 K. This is achieved by an intense pressure wave carefully focused inside a…
Time-resolved quantitative multiphase interferometric imaging of a highly focused ultrasound pulse
Fabien Souris, Jules Grucker, Philippe Jacquier +3
Interferometric imaging is a well established method to image phase objects by mixing the image wavefront with a reference one on a CCD camera. It has also been applied to fast tra…
Investigating metastable hcp solid helium below its melting pressure
Fabien Souris, Jules Grucker, Jacques Dupont-Roc +1
We report a first attempt to produce metastable hcp solid helium below its melting pressure. A focused sound pulse is emitted along the c-axis of a mono-domain hcp helium-4 crystal…
Negative-index media for matter-wave optics
J. Baudon, M. Hamamda, J. Grucker +4
We consider the extension of optical meta-materials to matter waves. We show that the generic property of pulsed comoving magnetic fields allows us to fashion the wave-number depen…
Nuclear spin interferences in bulk water at room temperature
Jules Grucker, Kees Van Schenk Brill, Edward Belaga +2
Nuclear spin interference effects generated in a macroscopic sample of 10ml degassed water are detected in a simple NMR experiment. A π/2 - τ- π/2 RF double pulse sequence (Ramsey…
