Twisting and binding matter waves with photons in a cavity

https://phys.org/news/2024-04-photons-cavity.html

"atomic recoil from atom interacting with photon was dampened by atoms exchanging momentum by exchanging corresponding photons. within mirrored cavity... this momentum-exchange interaction induces one-axis twisting (OAT), an aspect of quantum entanglement, between atomic momentum states... reduces quantum noise from multiple atoms, enabling entanglement momentum states improving measurements by quantum sensors, such as of gravitational waves... also mitigates Doppler shift... improve quantum devices"
