Scientists have made a significant leap in developing lasers that use sound waves instead of light. These phonon lasers hold promise for advancements in medical imaging, deep-sea exploration, and ...

In a new study published in Nature Physics, scientists have achieved the first experimental observation of phonon angular momentum in chiral crystals. Phonons are the quantized lattice vibrations ...

You may not be able to hear it, but all solid materials make a sound. In fact, atoms ⎯ bound in lattices of chemical ...

This makes phonon-polaritons ideal for high-tech applications like sub-wavelength imaging, molecular sensors, and heat management within electronics. However, research on phonon-polariton waves has ...
