In this paper we partially clarify the relation between the compressibility of a protein and its
molecular geometric structure. To identify and understand the relevant topological features …

Joint inelastic neutron and x-ray scattering measurements have been performed on heavy
water across the melting point. The spectra bear clear evidence of low-and high-frequency …

Picosecond time scale dynamics of hydrated proteins has been connected with the onset of
biological activity as it coincides with solvent–solute hydrogen bond rearrangements and …

Understanding how proteins work requires a thorough understanding of their internal
dynamics. Proteins support a wide range of motions, from the femtoseconds to seconds time …

The coherent density fluctuations of a perdeuterated dry protein have been studied by
Brillouin neutron spectroscopy. Besides a nearly wavevector-independent branch located …

We present an experimental study of the collective dynamics of lithium-ammonia solutions in
order to investigate the role played by the metallic character of the liquid on the atomic …

Phonons are quasi-particles, observed as lattice vibrations in periodic materials, that often
dampen in the presence of structural perturbations. Nevertheless, phonon-like collective …

High-resolution inelastic X-ray scattering was used to investigate the collective vibrational
excitations in hydrated lysozyme powders as a function of hydration level and temperature. It …

Summarising recent research on the physics of complex liquids, this in-depth analysis
examines the topic of complex liquids from a modern perspective, addressing experimental …

Femtosecond vibrational coherence spectroscopy is used to investigate the low frequency
vibrational dynamics of the electron transfer heme protein, cytochrome c (cyt c). The …
