Collective vibrational modes of crystal lattices, called phonons, determine fundamental material properties, such as their thermal and electrical conductivities. Bulk phonon spectra are influenced by ...

Using ultra-high-precision laser spectroscopy on a simple molecule, a group of physicists led by Professor Stephan Schiller Ph.D. from Heinrich Heine University Düsseldorf (HHU) has measured the ...

Figure 1: Spin-averaging and spin-polarized spectra of a Mn atom on a Cu 2 N/Cu(100) surface. Note added in proof: In the final stages of manuscript preparation, a similar theoretical description of ...

Using ultra-high-precision laser spectroscopy on a simple molecule, a group of physicists has measured the wave-like vibration of atomic nuclei with an unprecedented level of precision. The physicists ...

The wavelength dependent H atom and S atom spectra obtained following photodissociation of H2S molecules (A). The dominant transitions contributing to the four features are indicated. The 3D contour ...
