Scientific Achievement
Researchers experimentally demonstrated a room-temperature polariton supersolid phase using single-crystal perovskites integrated with a nanograting photonic structure, achieving the coexistence of superfluidity and crystalline order via spontaneous symmetry breaking.
Significance and Impact
The discovery provides a scalable and accessible platform for studying exotic quantum phases and many-body phenomena under ambient conditions, opening new opportunities for quantum simulation and next-generation photonic quantum technologies.
Research Details
- The nanograting structure was fabricated in the CNM cleanroom using a JEOL electron-beam lithography system and integrated with excitonic perovskite microplates to enable the observation and study of supersolid phases.
About Argonne’s Center for Nanoscale Materials
The Center for Nanoscale Materials is one of the five DOE Nanoscale Science Research Centers, premier national user facilities for interdisciplinary research at the nanoscale supported by the DOE Office of Science. Together the NSRCs comprise a suite of complementary facilities that provide researchers with state-of-the-art capabilities to fabricate, process, characterize and model nanoscale materials, and constitute the largest infrastructure investment of the National Nanotechnology Initiative. The NSRCs are located at DOE’s Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge, Sandia and Los Alamos National Laboratories.
