Physicists from the University of Nebraska-Lincoln and the University of California at Berkeley used a new method
The polariton system uses quantumhalf-light and half-matter quasi-particles, exciton-polaritons, as a solid-state analog photon simulation platform for quantum physics, such as Bose-Einstein condensate and complex XY models.
As the authors of the work note, suchSo far simulation has only been possible in polaritons operating at ultralow temperatures (about 270°C). With the new material, such studies can be carried out at room temperature.
“We show that the XY spin lattice with largenumber of coherently bound condensates can be constructed in the new material as a lattice up to 10x10,” says Xiang Zhang, president of the University of Hong Kong and a former professor at the University of California at Berkeley who took part in the study.
Physicists note that the solution synthesis method,described in the work, allows you to control the thickness of a large ultra-homogeneous perovskite during creation. The new technology, as the authors believe, will make it possible to conduct many quantum studies at room temperature without complex and expensive equipment and materials.
