Briefings

Researchers from the University of Warsaw, Military University of Technology, IBM Research Zurich, and CNRS successfully observed a supersolid quantum state in an exciton-polariton Bose-Einstein condensate. This breakthrough occurs at room temperature, challenging previous assumptions that such states require near-absolute-zero conditions. The findings were published in Science Advances.

Key points

• Researchers from the University of Warsaw, Military University of Technology, IBM Research Zurich, and CNRS observed a supersolid quantum state in an exciton-polariton Bose-Einstein condensate.
• The phenomenon occurs at room temperature, not near absolute zero, as confirmed by the study published in Science Advances.

Context

This discovery represents a significant advancement in quantum physics, as it demonstrates the existence of a supersolid state under conditions previously thought to be inaccessible at room temperature.

Limitations

The evidence is limited to the specific observation of a supersolid state in an exciton-polariton Bose-Einstein condensate. No further details on the experimental setup, duration, or broader implications are provided in the source.
