For the first time, we have demonstrated tunable generation of entangled photons in an organic material (a liquid crystal).
Vitaliy Sultanov, Aljaž Kavčič, Manolis Kokkinakis, Nerea Sebastián, Maria V. Chekhova, Matjaž Humar
We demonstrated for the first time that soap (and smectic) bubbles can be used as lasers. They are employed as extremely sensitive pressure and electric field sensors.
