@informaq.bsky.socialUltracold-atom collision study reveals sharply enhanced dynamical inertia of fast impurities in Bose-Einstein condensates near resonance, providing evidence for many-body polaron dressing in strongly coupled quantum regimes.
@jaceblog.bsky.socialFROM ATOMIC BEC TO QUANTUM MATTER
What comes after atomic BEC?
Molecular condensates, BECs in microgravity, and atom interferometry open new frontiers in quantum matter and precision sensing.
Matter became a wave. Now we learn how to control it.
@jaceblog.bsky.social38 PICOKELVIN
38 picokelvin was not simply a colder thermometer reading.
A matter-wave lens reduced the residual internal kinetic energy of a BEC to a 38 pK equivalent scale, slowing expansion for precise atom interferometry.

@jaceblog.bsky.socialHOW DO YOU COOL MATTER THAT FAR?
How do you cool matter to the edge of quantum degeneracy?
Laser cooling is only the beginning. Trapping, evaporation, thermalization, and the RF knife drive the cascade toward BEC.
