Quantum Dynamics and Cosmological Acceleration: A Unified Theory?

Physicists at Penn State have discovered a universal reaction in quantum systems when disturbed by a large influx of energy, using ultra-cold, one-dimensional gases, they were able to closely observe this response and the subsequent phase known as “hydrodynamization,” providing a model for understanding similar quantum systems. The findings were published in the journal Nature.

Revealing Universal Physics in Quantum Dynamics.

New experiments using ultra-cold atomic gases reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws the system out of equilibrium. Penn State physicists showed that these gases immediately respond, "evolving" with features that are common to all "many-body" quantum systems thrown out of equilibrium in this way. The experiment and theory together provide a model example of hydrodynamization, which happens so fast that the underlying understanding in terms of quasi-particles can be applied to any many-body quantum system to which a very large amount of energy is added.
