Vibrational modes in mechanical resonators provide a promising candidate to interface and manipulate classical and quantum information. The observation of coherent dynamics between distant mechanical ...

Schematics of the ultrafast broadband terahertz excitation and polarization rotation detection of phonon in WSe2. Obtained result (lower right) includes the coherent phonon oscillation signal excited ...

Researchers have demonstrated a novel concept for exciting and probing coherent phonons in crystals of a transiently broken symmetry. The key of this concept lies in reducing the symmetry of a crystal ...

Scientists have harnessed elliptical micropillars to enhance the generation and detection of coherent acoustic phonons in the gigahertz range. This advancement represents a significant step forward in ...

Two different waves with the same frequency and wavelengths can be coupled, so that the amplitude alternates periodically between the two to form a phenomenon known as a coherent beating oscillation.

Atoms in a crystal form a regular lattice, in which they can move over small distances from their equilibrium positions. Such phonon excitations are represented by quantum states. A superposition of ...
