New Theory Reveals Why a Quantum Gas Keeps Its Cool Under Energy Kicks
Physicists have built a theoretical framework linking interparticle interaction strength to the momentum-kick amplitude in a strongly interacting one-dimensional quantum gas, showing a critical regime where external energy stops being absorbed due to dynamical localization. The model explains why the gas resists heating, suggests the mechanism may apply to other quantum systems, and sets the stage for future experimental tests to explore finite-size and thermodynamic-limit behavior.
