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…
Efficient atomization of cesium metal in solid helium by low energy (10 J) femtosecond pulses
Mathieu Melich, Jacques Dupont-Roc, Philippe Jacquier
Metal atoms in solid and liquid helium-4 have attracted some interest either as a way to keep the atoms in a weakly perturbing matrix, or using them as a probe for the helium host…
Search for anisotropic effects of hcp solid helium on optical lines of cesium impurities
Mathieu Melich, Jacques Dupont-Roc, Philippe Jacquier
The anisotropic effect of a hcp 4He solid matrix on cesium atoms has been proposed as a tool to reveal the parity violating anapole moment of its nucleus. It should also result in…
