[Chinese team achieved important theoretical breakthrough in the field of quantum phase change] August 29th, the reporter learned from Ningbo Eastern University of Science and Technology on the 28th that Yu Xuejia’s team from the school, together with relevant research teams from Hunan University and Zhejiang University, achieved important theoretical breakthroughs in the field of quantum phase change and critical phenomena. For the first time, an anomalous dynamic behavior dominated by the topological edge state of the critical point is revealed, which challenges the Kibble-Zurek (KZ) mechanism in traditional quantum phase transition dynamics and opens up a new way to detect the topological properties of the critical point on modern quantum simulation platforms. Relevant results were published in the international physics journal Physical Review Letters. (Science and Technology Daily)
