Researchers from CIC nanoGUNE, in collaboration with the Donostia International Physics Center (DIPC) and the Center for Materials Physics (CFM), have experimentally observed and theoretically ...
(a) Phonon (wavy lines) absorption and (b) stimulated emission of so called longitudinal optical (LO) phonons schematically explained in the conduction band structure (black parabola: electron energy ...
(a) Schematic illustration of the magneto-optical Raman experiment. (b) Observation of chiral phonon behavior in the Bg4 mode. (c) Magneto-optical Raman effect (linear polarization). (d) ...
Researchers have captured the first direct, momentum-resolved evidence that certain lattice vibrations carry measurable magnetic signatures, using neutron spectroscopy on a specially engineered ...
Phonons, quasiparticles in a crystal lattice that are usually hard to control by external fields, can be manipulated by a magnetic field -- but it takes a very strong magnet. Phonons are collective ...
