Sound modes broadening in quasicrystals
M. de Boissieu, R. Currat, S. Francoual +1
We propose a simple phenomenological model to analyze vibrational characteristics of quasicrystals (QCs). The interpretation of the obtained recently data is based on the existence…

Energy-momentum tensor of quasiparticles in the effective gravity in superfluids
G. E. Volovik
The problem of the energy-momentum conservation for matter in the gravitational field is discussed on the example of the effective gravity, which arises in superfluids. The "gravit…
