The Sagnac effect in superfluids
E. Varoquaux, G. Varoquaux
We comment on the interpretation of absolute rotation measurements with superfluids, which involve the Sagnac effect. This effect, first observed in rotating optical interferometer…
Trapping electrons in electrostatic traps over the surface of helium
E. Rousseau, Y. Mukharsky, D. Ponarine +2
We have observed trapping of electrons in an electrostatic trap formed over the surface of liquid helium-4. These electrons are detected by a Single Electron Transistor located at…
Critical velocities in superfluids and the nucleation of vortices
E. Varoquaux
The problem of critical velocities in superfluids, that is the comprehension of superfluidity breakdown by flow, has been long standing. One difficulty stems from the existence of…
Search for supersolidity in 4He in low-frequency sound experiments
Yu. Mukharsky, O. Avenel, E. Varoquaux
We present results of the search for supersolid 4He using low-frequency, low-level mechanical excitation of a solid sample grown and cooled at fixed volume. We have observed low fr…
