Researchers observe localized phonon modes at a heterointerface

Phonons—the quasiparticle describing lattice vibrations in solids—directly dictates various properties of solid state systems, such as the thermal conductivity, electron mobility, structural stability and conventional ...

Amazonian river winds unraveled by air pollution observations

River winds are induced by the daily thermal contrast between the land and the river. During the daytime, warmer temperatures over the land lead to lighter air masses that are lifted. The air masses in turn drive onshore ...

Ultrafast electron dynamics in space and time

Often depicted as colorful balloons or clouds, electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of electrons in chemical reactions, ...
