The Dynamics of Quantum Fluids
Henri Godfrin, Eckhard Krotscheck
We review experimental and theoretical progress in the physical description of the dynamics of the quantum fluids \he4 and \he3. Historically, the elementary excitations in these s…
The dispersion relation of Landau elementary excitations and the thermodynamic properties of superfluid He
H. Godfrin, K. Beauvois, A. Sultan +4
The dispersion relation of the elementary excitations of superfluid He has been measured at very low temperatures, from saturated vapor pressure up to solidification, us…
Transport and Phonon Damping in He
K. Beauvois, H. Godfrin, E. Krotscheck +1
The dynamic structure function informs about the dispersion and damping of excitations. We have recently (Phys. Rev. B {\bf 97}, 184520 (2018)) compared experimental resul…
Silicon Vibrating Wires at Low Temperatures
Eddy Collin, Laure Filleau, Thierry Fournier +2
Nowadays microfabrication techniques originating from micro-electronics enable to create mechanical objects of micron-size. The field of Micro-Electro-Mechanical devices (MEMS) is…
Microscopic dynamics of superfluid He: a comprehensive study by inelastic neutron scattering
K. Beauvois, J. Dawidowski, B. Fåk +4
The dynamic structure factor of superfluid He has been investigated at very low temperatures by inelastic neutron scattering. The measurements combine different incoming energi…
Superfluid 4He dynamics beyond quasiparticle excitations
K. Beauvois, C. E. Campbell, J. Dawidowski +7
The dynamics of superfluid 4He at and above the Landau quasiparticle regime is investigated by high precision inelastic neutron scattering measurements of the dynamic structure fac…
