You can create a bizarre quantum state of matter without cooling it down, simply by 'shaking' it in exactly the right way.

The Takeaway
This identifies a 'non-thermal' pathway to creating Bose-Einstein Condensates using nonlinear energy cascades. It suggests that quantum order can emerge from a specific type of drive rather than just extreme refrigeration, potentially making quantum states easier to produce.
From the abstract
In this paper, we study a system of bosons trapped in a confining potential, interacting with a quantized field of coherent photons in the mean field description of non-relativistic Quantum Electrodynamics (QED) obtained by [N. Leopold and P. Pickl , 2017]. We derive the effective nonlinear cascade equations governing the emission and absorption of coherent photons by the boson subsystem in a combined weak-coupling and kinetic-scaling limit. We demonstrate that solutions to this nonlinear cascad
