Coherent coupling of trapped ion mechanical oscillators for quantum information processing
I will present our recent progress in the coherent coupling of spectrally separated harmonic modes of motion of a trapped ion crystal and its applications. We realize high-fidelity coherent exchange o...

奇特强子态与强子结构
强子，包括介子和重子，是能从物质中分离出来的、已观测到具有内部结构的最小单元。寻找新强子态、探索强子内部的夸克-胶子结构是粒子物理和中高能核物理共同关心的交叉前沿课题。近年来，越来越多的超出经典夸克模型...

Scaling of the strange-metal scattering in high-Tc superconductors
Soon after the discovery of cuprate superconductors, the strange-metal behavior of their normal-state resistivity was observed, namely, a linear resistivity as a function of temperature (T-linear resi...

Symmetry control and emergent phenomena in square-lattice iridates
Spin-orbit coupling (SOC) is a key ingredient of nontrivial band topology in weakly interacting materials. On the other hand, the impact of SOC in strongly correlated systems often manifests in magnet...

基准钟研究及秒定义变革
基准钟是直接复现秒定义的原子钟。目前铯原子喷泉基准钟的相对频率不确定度A类(稳定度)已经达到E-16@1 d，B类达到(1-2)E-16，主要受限于微波相关频移。随着原子操控和超稳激光技术的发展，光钟频率不确定度已经比现在...
