abstract = {From inelastic neutron-scattering experiments and all atom
molecular dynamics simulations we present evidence for a
low-energy dynamical mode in the fluid phase of a
1,2-dimyristoyl-sn-glycero-3-phoshatidylcholine (DMPC)
bilayer immersed in a $5\%$ water/ethanol solution. In
addition to the well-known phonon that shows a liquidlike
dispersion with energies up to 4.5 meV, we observe an
additional mode at smaller energies of 0.8 meV, which shows
little or no dispersion. Both modes show transverse
properties and might be related to molecular motion
perpendicular to the bilayer.},
