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…
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…
Dynamic many-body theory: Dynamic structure factor of two-dimensional liquid He
Eckhard Krotscheck, Thomas Lichtenegger
We calculate the dynamic structure function of two-dimensional liquid He at zero temperature employing a quantitative multi-particle fluctuations approach up to infinite order.…
Dynamic Many-Body Theory. II. Dynamics of Strongly Correlated Fermi Fluids
H. M. Böhm, R. Holler, E. Krotscheck +1
We develop a systematic theory of multi-particle excitations in strongly interacting Fermi systems. Our work is the generalization of the time-honored work by Jackson, Feenberg, an…
