Recently, Li Xiaopeng's research team, working in tandem with Professor Qi Yang of Fudan University and Researcher Yan Zheng from Westlake University, employed a Rydberg neutral atom quantum simulation platform to, for the very first time, unveil the quantum state known as “double supersolidity” within the bosonic t-J-V model. This unique state simultaneously showcases the defining features of crystalline order, hole superfluidity, and spin superfluidity, thereby shedding light on the intricate synergistic mechanism that arises from long-range tunneling and robust interactions. This groundbreaking discovery paves the way for a fresh perspective on investigating the charge-spin competition mechanism inherent in high-temperature superconductivity. The experimental endeavors were bolstered by Fudan University's rubidium/cesium atom array platform, coupled with the high-performance computing resources provided by Westlake University. The pertinent findings have been duly published in the esteemed journal Physical Review Letters.
