Anderson's considerations on the flow of superfluid helium: some offshoots
Eric Varoquaux
Nearly five decades have elapsed since the seminal 1966 paper of P.W. Anderson on the flow of superfluid helium, He at that time. Some of his "Considerations" -- the role of th…
The low temperature elastic anomalies in solid helium
Eric Varoquaux
The elastic properties of hcp He samples have been shown to display various anomalies. The elastic shear modulus stiffens and the moment of rotational inertia drops when the te…
Wigner islands with electrons over helium
E. Rousseau, D. Ponarin, L. Hristakos +3
We present here the first experimental study of Wigner islands formed by electrons floating over helium. Electrons are trapped electrostatically in a mesoscopic structure covered w…
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…
