Soft modes in crystals are lattice vibrations with frequencies that decrease and eventually vanish as the temperature approaches a critical point, e.g., a structural change due to a phase transition. In ionic para- or ferroelectric materials, the fre

The coupled lattice and charge dynamics induced by phonon excitation in polycrystalline acetylsalicylic acid (aspirin) are mapped by femtosecond x-ray powder diffraction. The hybrid-mode character of the 0.9 ± 0.1 THz methyl rotation in the aspirin

Este artículo considera la idea del cine transnacional desde varias perspectivas distintas: primero, como un término que compite con otros -tales como “cine del mundo”, “cine independiente”, “cine con acento” o “cine periférico”-,

Durant gairebé cent anys, la imatge en moviment s'ha tractat principalment des de la perspectiva de la fotografia i hem organitzat les nostres preguntes i teories sobre el cinema com a dispositiu ocular, basat en la llum, la projecció i la transpar

Quantum theory has linked microscopic currents and macroscopic polarizations of ferroelectrics, but the interplay of lattice excitations and charge dynamics on atomic length and time scales is an open problem. Upon phonon excitation in the prototypic

Table-top laser-driven hard x-ray sources with kilohertz repetition rates are an attractive alternative to large-scale accelerator-based systems and have found widespread applications in x-ray studies of ultrafast structural dynamics. Hard x-ray pu

Molecular couplings between DNA and water together with the accompanying processes of energy exchange are mapped via the ultrafast response of DNA backbone vibrations after OH stretch excitation of the water shell. Native salmon testes DNA is stud

The structure and function of biomolecules can be strongly influenced by their hydration shells. A key challenge is thus to determine the extent to which these shells differ from bulk water, since the structural fluctuations and molecular excitations

Seen from today’s vantage point, Siegfried Kracauer’s Theory of Film (1960) envisages the possibility that the cinema may turn out to have been a historical phenomenon whose technological specifications as well as aesthetic properties are conting

DNA oligomers are studied at 0% and 92% relative humidity, corresponding to N 20 water molecules per base pair. Two-dimensional (2D) infrared spectroscopy of DNA backbone modes between 920 and 1120 cm−1 maps fluctuating interactions at the DNA surf
