UT Austin, Max Planck Reveal Room-Temp Chiral Light Coupling

5/5/2026

Summary

Story summary

UT Austin and the Max Planck Institute in Hamburg discovered resonant chiral dressing linking forbidden vibrations.
Using helicity-resolved light scattering, they found a peak when the amplitudon matched a phonon.
Temperature tuning shifted the amplitudon energy, producing maximal left-right asymmetry attributed to charge-density-wave fluctuations.
Theoretical work showed the amplitudon mediates resonant coupling, with Michael Rübhausen’s group confirming the effect persists at room temperature, enabling light control of quantum states.
